Title: Fatal error when customizing theme Last modified: August 21, 2016 --- # Fatal error when customizing theme * [RSguideMaker](https://wordpress.org/support/users/rsguidemaker/) * (@rsguidemaker) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-when-customizing-theme/) * Hi there, I have been encountering this error ever since I changed my theme. I prefer the new theme, but I can customize it due to this error I keep encountering: [http://img854.imageshack.us/img854/2532/qnfd.png](http://img854.imageshack.us/img854/2532/qnfd.png) * I originally contacted the support on my hosts to see whether they could solve the issue, and they recommended I opened a topic here. As I said, this issue has only come about since I installed a new theme. I know it’s not the theme because it runs perfectly on a separate site which I use for testing themes first. The site which I am having the issue with is [http://www.euanfitzpatrick.co.nf/](http://www.euanfitzpatrick.co.nf/) * Any help would be appreciated, Euan Fitzpatrick Viewing 9 replies - 1 through 9 (of 9 total) * [WPyogi](https://wordpress.org/support/users/wpyogi/) * (@wpyogi) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-when-customizing-theme/#post-4040185) * Please deactivate ALL plugins and switch to the twentytwelve theme to see if that solves the problem. * Thread Starter [RSguideMaker](https://wordpress.org/support/users/rsguidemaker/) * (@rsguidemaker) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-when-customizing-theme/#post-4040200) * The Twenty Twelve theme works, however I still receive errors. I’m receiving errors whilst trying to update the theme: [http://img138.imageshack.us/img138/9514/wdmf.png](http://img138.imageshack.us/img138/9514/wdmf.png) * Moderator [t-p](https://wordpress.org/support/users/t-p/) * (@t-p) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-when-customizing-theme/#post-4040225) * > The Twenty Twelve theme works, however I still receive errors. * Not clear – doe twenty Twelve works ot not? * I assume what you are trying to say is that the Twenty Twelve works but your theme does not. Is my assumtion correcrt? * If so, it suggests that your theme is broken. * Thread Starter [RSguideMaker](https://wordpress.org/support/users/rsguidemaker/) * (@rsguidemaker) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-when-customizing-theme/#post-4040258) * Twenty twelve works as per say, however I still receive errors whenever I try to do administrative things. I can’t edit posts, nor can I update the WP version or the plugins. Also, the theme works perfectly on a separate domain – no issues whatsoever. * Moderator [t-p](https://wordpress.org/support/users/t-p/) * (@t-p) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-when-customizing-theme/#post-4040261) * > Twenty twelve works as per say, however I still receive errors whenever I > try to do administrative things. * – What is the full error? * – Have you tried [resetting the plugins ](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F) folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems (because the hooks remain unless plugins completely removed or some plugins stick around in cached files. So by renaming the folder, you break them and force them inactive). * Thread Starter [RSguideMaker](https://wordpress.org/support/users/rsguidemaker/) * (@rsguidemaker) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-when-customizing-theme/#post-4040295) * I used the FTP method to reset the plugins, and then I got this message whilst trying to update a theme: [http://img853.imageshack.us/img853/1088/1cv.png](http://img853.imageshack.us/img853/1088/1cv.png) * Surely that shouldn’t be the case? * Thread Starter [RSguideMaker](https://wordpress.org/support/users/rsguidemaker/) * (@rsguidemaker) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-when-customizing-theme/#post-4040335) * Help please? :/ * [leejosepho](https://wordpress.org/support/users/leejosepho/) * (@leejosepho) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-when-customizing-theme/#post-4040336) * Is this similar to what happened last time? [http://wordpress.org/support/topic/unscheduled-maintenance-error?replies=1](http://wordpress.org/support/topic/unscheduled-maintenance-error?replies=1) * If so, do you remember what you did then? * I do not know very much about `.htaccess`, but you might try replacing that file with a default via FTP to see whether that might knock that maintenance block out of the way. * Thread Starter [RSguideMaker](https://wordpress.org/support/users/rsguidemaker/) * (@rsguidemaker) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-when-customizing-theme/#post-4040342) * Yes, it’s the exact same problem. It keeps hapenning, and I didn’t end up doing anything to sort it out last time. I’ll have a look at the `.htaccess` file and see whether I can resolve the issue. I didn’t think about the `.htaccess` file initially.
