Title: Fatal Error. Last modified: August 20, 2016 --- # Fatal Error. * [esljosh](https://wordpress.org/support/users/esljosh/) * (@esljosh) * [14 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-377/) * I just updated your plugin and now it won’t let me activate it because of a “ fatal error” * This is the error I am getting when I try to activate the plugin. * “Plugin could not be activated because it triggered a fatal error.” Viewing 12 replies - 1 through 12 (of 12 total) * Plugin Author [DCoda](https://wordpress.org/support/users/dcoda/) * (@dcoda) * [14 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-377/#post-2270289) * I’ve downloaded and tested the plugin that is posted on the site and it works as expected. Fatal error can cover many things, so may i ask how did you upgrade? Manually or through WordPress. * If manually, did you delete the old version as stated in the instructions? Some files have been removed from the project and there presence will cause problems if they are still there. * If automatically, can I ask you to try to activate it manually as the main file has changed and this could be the cause in this situation. * Regards DCoda * Thread Starter [esljosh](https://wordpress.org/support/users/esljosh/) * (@esljosh) * [14 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-377/#post-2270302) * DCoda, I activated it through the wordpress interface. I can go ahead and delete the files and re-install manually, but I don’t want to lose all of my quizzes from before. Where are those quizzes stored and will I lose them by manually reinstalling? * Thanks for the quick reply as usual! * Plugin Author [DCoda](https://wordpress.org/support/users/dcoda/) * (@dcoda) * [14 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-377/#post-2270322) * I’m not sure how the WordPress interface works, but we did change the name of the main plugin file so If WordPress assumes its the same that could be the problem. If this is the case, then just clicking activate on the plugins screen should work. * Your data safe, it is storred in the database, so unless you have customised the plugin files you will not loose anything by deleting the plugin files. * Thread Starter [esljosh](https://wordpress.org/support/users/esljosh/) * (@esljosh) * [14 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-377/#post-2270339) * I deleted all of the files in the plugin folder named “quizme” from the previous version. Then I uploaded all of the folders in the new “quizme” folder in the zip file that I downloaded for version 2.5.33. * It is still saying fatal error when I try to activate the plugin from the plugin screen. What else could be causing this plugin to cause a fatal error? * I also tried deleting it again and re-installing it through the wordpress site and that didn’t work either. I don’t know what else to try. * Plugin Author [DCoda](https://wordpress.org/support/users/dcoda/) * (@dcoda) * [14 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-377/#post-2270354) * What operating system are you on, do you know if it’s case sensitive. This may be the problem, and assuming this is the problem and working to find the offending file that is in the wrong case. * You can find the old versions here [http://wordpress.org/extend/plugins/quizme/download/](http://wordpress.org/extend/plugins/quizme/download/) So you can continue to run while we look into the problem * Thread Starter [esljosh](https://wordpress.org/support/users/esljosh/) * (@esljosh) * [14 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-377/#post-2270363) * I have tried it on a Mac and a PC and neither are working. If it is case sensitive, I just followed the naming convention that you used to name your files, so I am not sure how that could mess things up. * In the meantime I have installed the old version (2.5.28) and that is working just fine. Thanks. * Plugin Author [DCoda](https://wordpress.org/support/users/dcoda/) * (@dcoda) * [14 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-377/#post-2270379) * HHHmmm, both windows and osx ( usually ) are case insensitive. So this cannot be the cause. and yet the old versions work fine. Can I ask what PHP version you are using, maybe a function that is not PHP 5.2 compliant has been used. * Thread Starter [esljosh](https://wordpress.org/support/users/esljosh/) * (@esljosh) * [14 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-377/#post-2270385) * I am running PHP version 5.2.17. * Plugin Author [DCoda](https://wordpress.org/support/users/dcoda/) * (@dcoda) * [14 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-377/#post-2270438) * Since you are PHP 5.2 and the minimum we have available for us to test is 5.3 it seems probable that some functions that require 5.2 have been used. Well look though all the new code to see if this is the case. * [rebthegreat](https://wordpress.org/support/users/rebthegreat/) * (@rebthegreat) * [14 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-377/#post-2270480) * Our hosting running PHP 5.2. Is there a previous version of the plugin available for download? * [rebthegreat](https://wordpress.org/support/users/rebthegreat/) * (@rebthegreat) * [14 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-377/#post-2270481) * Oh nevermind, found the tiny link to previous versions: [http://wordpress.org/extend/plugins/quizme/download/](http://wordpress.org/extend/plugins/quizme/download/) * Plugin Author [DCoda](https://wordpress.org/support/users/dcoda/) * (@dcoda) * [14 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-377/#post-2270482) * We are down grading all our development servers, and hopefully this be something that can be easily fixed with 5.2 code only. We do intend to go back to 5.2 compliance.
