Title: Upgrade failed Last modified: August 22, 2016 --- # Upgrade failed * [jameshill](https://wordpress.org/support/users/jameshill/) * (@jameshill) * [11 years, 9 months ago](https://wordpress.org/support/topic/upgrade-failed-10/) * Failing at upgrading directly to WP 4.0 returned to 3.3.1. Upgrade outdated plug- ins then tried Blaskan which shows a blank page. Meanwhile, other themes work. I love Blaskan and would like it back. * [https://wordpress.org/themes/blaskan/](https://wordpress.org/themes/blaskan/) Viewing 11 replies - 1 through 11 (of 11 total) * Thread Starter [jameshill](https://wordpress.org/support/users/jameshill/) * (@jameshill) * [11 years, 9 months ago](https://wordpress.org/support/topic/upgrade-failed-10/#post-5275704) * Have succeeded at replacing old file of Blaskan successfully in root folder. Will not upgrade, although now I wonder if the old Blaskan was interfering with a successful upgrade of WP to 4.0. * [doume](https://wordpress.org/support/users/doume/) * (@doume) * [11 years, 7 months ago](https://wordpress.org/support/topic/upgrade-failed-10/#post-5276003) * I use native Blaskan plus a Blaskan Child Theme since it was launched and never had any problem when upgrading WP, which is done every time an upgrade is available. Switch from PHP 5.2.13 to 5.4.26 was OK too. * [sleeplessindc](https://wordpress.org/support/users/sleeplessindc/) * (@sleeplessindc) * [11 years, 7 months ago](https://wordpress.org/support/topic/upgrade-failed-10/#post-5276004) * I just tried to update to the new theme version 2.6.6 and now I get a blank page when I go to my site. * I am using WordPres 4.0 Tried it on Firefox 33.02 and Google Chrome 38.0.2125.111 I am using a Blaskan Child theme.

I went to Appearance / Themes and clicked on the base Blaskan Theme Details. It tells you that you have the new version 2.6.6 but it isn’t active. I know, you want your child theme to be active but ignore that for now. Click the Activate button for the base Blaskan theme. Return to your site and your site is back and using your child theme. * [sleeplessindc](https://wordpress.org/support/users/sleeplessindc/) * (@sleeplessindc) * [11 years, 7 months ago](https://wordpress.org/support/topic/upgrade-failed-10/#post-5276006) * No–I take that back. I logged out and then back in and noticed that the child theme was not being used. I went to Appearance / Themes and the base Blaskan was active and primary. So I activated my child theme and now I am back to a blank page. * Hopefullly, if I reinstall the Blaskan 2.6.5, I’ll get my site back. * [sleeplessindc](https://wordpress.org/support/users/sleeplessindc/) * (@sleeplessindc) * [11 years, 7 months ago](https://wordpress.org/support/topic/upgrade-failed-10/#post-5276007) * Yes–child theme works again now after I reinstalled Blaskan 2.6.5. * [doume](https://wordpress.org/support/users/doume/) * (@doume) * [11 years, 7 months ago](https://wordpress.org/support/topic/upgrade-failed-10/#post-5276008) * [@sleeplessindc](https://wordpress.org/support/users/sleeplessindc/) Just did the following test locally using XAMMP Win32-182-5-VC9 (PHP 5.4.27 is close to the version of my production server). Clean install of Blaskan 2.6.4 (previous version) + my production Child and no plugin then upgrade Blaskan => works. * [sleeplessindc](https://wordpress.org/support/users/sleeplessindc/) * (@sleeplessindc) * [11 years, 7 months ago](https://wordpress.org/support/topic/upgrade-failed-10/#post-5276009) * [@doume](https://wordpress.org/support/users/doume/) I tried turning off all the plugins, deleting the previous version of Blaskan that I had installed (2.6.5) and my Blaskan-Child. Then I installed Blaskan version 2.6.6 and my Blaskan-Child. I made my Child the active theme and I still get a blank page. This doesn’t work. * Dropping back down to Blaskan 2.6.5. * [sleeplessindc](https://wordpress.org/support/users/sleeplessindc/) * (@sleeplessindc) * [11 years, 7 months ago](https://wordpress.org/support/topic/upgrade-failed-10/#post-5276010) * Correction: I don’t know why I thought I had version 2.6.5. My previous version is 2.6.4. It works with my child theme but 2.6.6 doesn’t. * [doume](https://wordpress.org/support/users/doume/) * (@doume) * [11 years, 7 months ago](https://wordpress.org/support/topic/upgrade-failed-10/#post-5276011) * So alone or with Child it doesn’t work. I would say there is a problem between Child style or Child function and the evolutions made between 2.6.4 and 2.6.6. You can easily find them [here](https://github.com/persand/blaskan) and start from that. * [sleeplessindc](https://wordpress.org/support/users/sleeplessindc/) * (@sleeplessindc) * [11 years, 7 months ago](https://wordpress.org/support/topic/upgrade-failed-10/#post-5276012) * I found the problem. A line in the Blaskan-Child header.php had to be changed to match Line 10 in the 2.6.6 header for the Title. * My Child theme now works with Blaskan 2.6.6 Viewing 11 replies - 1 through 11 (of 11 total) The topic ‘Upgrade failed’ is closed to new replies. * ![](https://i0.wp.com/themes.svn.wordpress.org/blaskan/3.0.1/screenshot.jpg) * Blaskan * [Support Threads](https://wordpress.org/support/theme/blaskan/) * [Active Topics](https://wordpress.org/support/theme/blaskan/active/) * [Unresolved Topics](https://wordpress.org/support/theme/blaskan/unresolved/) * [Reviews](https://wordpress.org/support/theme/blaskan/reviews/) * 11 replies * 3 participants * Last reply from: [sleeplessindc](https://wordpress.org/support/users/sleeplessindc/) * Last activity: [11 years, 7 months ago](https://wordpress.org/support/topic/upgrade-failed-10/#post-5276012) * Status: not resolved
