Title: Network update under WP 3.1 Last modified: August 19, 2016 --- # Network update under WP 3.1 * Resolved [Thomas](https://wordpress.org/support/users/thomasbenlevigmailcom/) * (@thomasbenlevigmailcom) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/) * Hello, * I try in local to upgrade a WP network from 3.0 to 3.1. It seems ok (except some plugins that are not compatible) but i have a problem with the update of my network, after the update of 4 or 5 child blogs the update stop and i see the following message : Fatal error: Maximum execution time * I can’t increase the execution time, those 4 or 5 blogs work perfectly but the others display now a blank page in front page, so my question, is it possible to manually do this update for each of my blogs ? * Many thanks Thomas Viewing 15 replies - 1 through 15 (of 16 total) 1 [2](https://wordpress.org/support/topic/network-update-under-wp-31/page/2/?output_format=md) [→](https://wordpress.org/support/topic/network-update-under-wp-31/page/2/?output_format=md) * [Andrea Rennick](https://wordpress.org/support/users/andrea_r/) * (@andrea_r) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007063) * Yes, login to the admin area of each one. it fires the same process. * And a blank white page means a php error. Likely one of the plugins. Find the error logs on the server. * Thread Starter [Thomas](https://wordpress.org/support/users/thomasbenlevigmailcom/) * (@thomasbenlevigmailcom) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007161) * Hello Andrea, * Many thanks but i can’t find any update link for my child blogs, could you please tell where you find it ? When i’m in network admin i can see it but that’s all. * At this time only updated blogs display properly, the others display a blank page. * Thanks Thomas * [Tim Moore](https://wordpress.org/support/users/tmoorewp/) * (@tmoorewp) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007168) * Just by logging in, the upgrade process is fired. There isn’t a link to click. * Also, as Andrea pointed out, blank pages are PHP errors. You need to dig into your server’s error logs and find out what is going on. * [Andrea Rennick](https://wordpress.org/support/users/andrea_r/) * (@andrea_r) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007170) * > Many thanks but i can’t find any update link for my child blogs, could you > please tell where you find it ? * > login to the admin area of each one. it fires the same process. * Thus, there’s no link to click, like tim said * And a blank page is a php error, again – you need to find the error logs on the server. We don;t know what’s going on either. * Thread Starter [Thomas](https://wordpress.org/support/users/thomasbenlevigmailcom/) * (@thomasbenlevigmailcom) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007172) * OK thanks for your help i will search. * Thomas * [slob100](https://wordpress.org/support/users/slob100/) * (@slob100) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007237) * I have exact same problem for almost a month. I posted several questions, I read and tried almost everything. I even upgraded manualy to 3.1.1 (automatic upgrade doesn’t work, as well as Network admin, Install new plugins, Editor… and who knows what else). At one thread I read solving problem by changing wp-config: define(‘SITE_ID_CURRENT_SITE, 7) define(‘BLOG_ID_CURRENT_SITE, 7) * Author didn’t explain why “7”, default is “1”, but he had 7 subdomains. So, I have 2 subdomains and I tried with 2 – but nothing happens. * The site is working, in fact I can do whatever I want (via FTP), but it is annoying * Thread Starter [Thomas](https://wordpress.org/support/users/thomasbenlevigmailcom/) * (@thomasbenlevigmailcom) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007238) * Hello Slob, * I don’t understand what is your problem. * Only a few part of your child blogs are updated and the update process has stopped? * In my case, that was the problem, the network update has stopped before it update all blogs and now, those that have been updated work perfectly but the others display blank page. * Andrea & Tim tell me that this blank page means a php error but i don’t understand why the updated blogs works but not the others, i use the same theme and the same plugins… * Thomas * [slob100](https://wordpress.org/support/users/slob100/) * (@slob100) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007239) * oh no… I never updated Network – I can’t access Network admin at all.. I can’t access Install new plugins, Editor…, either. It’s been happening since I upgraded to WP 3.1, and now even to 3.1.1. manualy. I also have blank page (in Firefox). Try different browser, you might get some message. * Thread Starter [Thomas](https://wordpress.org/support/users/thomasbenlevigmailcom/) * (@thomasbenlevigmailcom) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007240) * I had the same problem with some of my MU networks, it was because of incompatibility with plugins (Wp Theme Switcher in my case). * [Andrea Rennick](https://wordpress.org/support/users/andrea_r/) * (@andrea_r) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007241) * > At one thread I read solving problem by changing wp-config: > define(‘SITE_ID_CURRENT_SITE, > 7) define(‘BLOG_ID_CURRENT_SITE, 7) > Author didn’t explain why “7”, default is “1”, but he had 7 subdomains. So, > I have 2 subdomains and I tried with 2 – but nothing happens. * that’s a good way to break things. * The number in those define declares what blog ID is your MAIN site. By default it is one. It has no relation to the number of sites you have. * And please – disable *all* your plugins. * [slob100](https://wordpress.org/support/users/slob100/) * (@slob100) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007242) * god… it was THEME here!!! I erased all plugins, I reinstalled whole WP… and it was THEME all the time! (“Gemer” at my case – and it doesn’t cause any other problem, just Network since 3.1) * [Mike Rawlins](https://wordpress.org/support/users/mikey_r/) * (@mikey_r) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007243) * I’ve just upgraded to 3.1 when I click on the Update Network link to go to mydomain. com/wp-admin/network/upgrade.php I end up in a redirect loop that fails. Safari returns: Too many redirects occurred trying to open “http://mydomain.com/wp-admin/ network/”. This might occur if you open a page that is redirected to open another page which then is redirected to open the original page. * Nothing has changed on my install in months no new plugins no new sites nothing. any ideas? * [Andrea Rennick](https://wordpress.org/support/users/andrea_r/) * (@andrea_r) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007250) * I’ve been finding in some threads, certain hosts don’t like rendering that nested admin folder. * [Mike Rawlins](https://wordpress.org/support/users/mikey_r/) * (@mikey_r) * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007275) * I’ve been away for a couple of days so sorry for the late reply. * I have other installs that run on the same host that run without any issues :/ * Moderator [Ipstenu (Mika Epstein)](https://wordpress.org/support/users/ipstenu/) * (@ipstenu) * 🏳️‍🌈 Advisor and Activist * [15 years, 1 month ago](https://wordpress.org/support/topic/network-update-under-wp-31/#post-2007276) * Not all accounts on a host are created equal. * By ‘host’ do you mean ‘all accounts are hosted on the same VPS server’ or just‘ I have multiple accounts on a webhost, spread across their myriad servers’?
