Title: White Screen after Multisite Update. Last modified: August 20, 2016 --- # White Screen after Multisite Update. * [craigtommola](https://wordpress.org/support/users/craigtommola/) * (@craigtommola) * [14 years, 6 months ago](https://wordpress.org/support/topic/white-screen-after-multisite-update/) * Greetings – I am hoping that this is a simple issue which I have simply overlooked, and you’ll easily be able to help remedy. * Multisite on 3.1.4 – 8 subsites set up as subdomain * I have tried every type of upgrade there is – automatic, manual – short instructions, manual – long instructions, etc. * I have backed the live site up and set it up locally. I have deactivated all plugins. * I get a white screen on front end and backend *every time*. I’ve tried about 6 times. I am close to simply starting with a whole new install and building the network from scratch, importing all content through XML files, and seeing if that works. * Thoughts? Any insight greatly appreciated.

The White Screen of Death is normally a PHP error. * Thread Starter [craigtommola](https://wordpress.org/support/users/craigtommola/) * (@craigtommola) * [14 years, 6 months ago](https://wordpress.org/support/topic/white-screen-after-multisite-update/#post-2367986) * I’m not sure what I’m looking for in the logs, however I see no php error mention. I restarted MAMP PRO, then tried to login to /wp-admin and still have white screen. No error shows in log. * Moderator [Ipstenu (Mika Epstein)](https://wordpress.org/support/users/ipstenu/) * (@ipstenu) * 🏳️‍🌈 Advisor and Activist * [14 years, 6 months ago](https://wordpress.org/support/topic/white-screen-after-multisite-update/#post-2367996) * You’re seeing the same error locally as on the network? * Locally, delete all your themes EXCEPT for twentyeleven (just kill ’em from the folder). * Thread Starter [craigtommola](https://wordpress.org/support/users/craigtommola/) * (@craigtommola) * [14 years, 6 months ago](https://wordpress.org/support/topic/white-screen-after-multisite-update/#post-2368035) * Crap – you’re a genius – I didn’t deactivate the theme. After removing themes from the themes folder, I have access to the admin, but still white page on frontend. * I Network activated Twenty Eleven. I then went to each site of the Network and activated Twenty Eleven. (each /themes.php page showed that the currently active theme was “broken”) I moved the previous contents of the themes folder back to the themes folder and proceeded to the /network/themes.php page. All needed themes were shown, and those which were previously network enabled, were automatically enabled again. I updated all themes. I updated all plugins. I returned to each of the /themes.php pages, and re-activated the intended theme. I returned to the /network/plugins.php page and re-network-activated the required plugins. I returned to each of the /plugins.php page and re-network-activated the required plugins. I am currently going through all plugin settings and confirming accuracy against live site. * I’ll let you know of further anomalies – thank you kindly. * In short, it seems that my first and only error had been not setting Twenty Eleven as the currently active theme, at the same time that I deactivated all plugins. * Moderator [Ipstenu (Mika Epstein)](https://wordpress.org/support/users/ipstenu/) * (@ipstenu) * 🏳️‍🌈 Advisor and Activist * [14 years, 6 months ago](https://wordpress.org/support/topic/white-screen-after-multisite-update/#post-2368052) * And that’s an easy mistake to make. It’s a bummer when it’s a theme issue, though! Usually the error log will spit out something to do with the functions.php when it’s that. * Thread Starter [craigtommola](https://wordpress.org/support/users/craigtommola/) * (@craigtommola) * [14 years, 6 months ago](https://wordpress.org/support/topic/white-screen-after-multisite-update/#post-2368095) * Actually, the instruction to deactivate all themes and activate default isn’t even in the manual upgrade instructions – I think it’s been some time since this post has been scrutinized and updated: * [http://codex.wordpress.org/Upgrading_WordPress_Extended](http://codex.wordpress.org/Upgrading_WordPress_Extended) * Thank you much for your help … I’m down to one last plugin update … WP e-Commerce… fingers crossed. * CT * Moderator [Ipstenu (Mika Epstein)](https://wordpress.org/support/users/ipstenu/) * (@ipstenu) * 🏳️‍🌈 Advisor and Activist * [14 years, 6 months ago](https://wordpress.org/support/topic/white-screen-after-multisite-update/#post-2368103) * > Actually, the instruction to deactivate all themes and activate default isn’t > even in the manual upgrade instructions * Because you don’t have to _most of the time_.
