Title: Fatal error on plugin update Last modified: August 31, 2016 --- # Fatal error on plugin update * [lilpenny1316](https://wordpress.org/support/users/lilpenny1316/) * (@lilpenny1316) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/) * I have the newest version of WordPress and Gravity Forms and I am unable to update the plugin. I get a 500 Internal Server error. When I try to update the plugin via phpmyadmin, the fatal error says that it cannot find this file: /wp-content/ plugins/gravity-forms-data-persistence-add-on-reloaded/persistent_multipage_forms- reloaded.php * Do I need to rollback to a previous version? * [https://wordpress.org/plugins/gravity-forms-data-persistence-add-on-reloaded/](https://wordpress.org/plugins/gravity-forms-data-persistence-add-on-reloaded/) Viewing 15 replies - 1 through 15 (of 15 total) * Plugin Author [unclhos](https://wordpress.org/support/users/unclhos/) * (@unclhos) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051185) * Just deactivate and reactivate. I changed the file name to name if plugin like it should have been. Didnt know it would cause a problem. * Thread Starter [lilpenny1316](https://wordpress.org/support/users/lilpenny1316/) * (@lilpenny1316) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051214) * That does not fix the situation. I even deleted the plugin and reinstalled. Every time I try to activate the plugin, the browser hangs until I get a 500 Internal Server Error. Is it possible to rename the PHP file in the plugin folder or will that also not work? * Thanks! * Plugin Author [unclhos](https://wordpress.org/support/users/unclhos/) * (@unclhos) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051241) * Can you give me the full error? This sounds like something is coded to call that file for some reason. WordPress normally gracefully “deactivates” plugins it can’t find. And then if you reactivate it would be like activated a completely new plugin. * Plugin Author [unclhos](https://wordpress.org/support/users/unclhos/) * (@unclhos) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051242) * Also WordPress show there have been over 100 installs/updates since this release and you are the first to say anything. * Thread Starter [lilpenny1316](https://wordpress.org/support/users/lilpenny1316/) * (@lilpenny1316) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051252) * Here’s the error message: * The plugin gravity-forms-data-persistence-add-on-reloaded/persistent_multipage_forms- reloaded.php has been deactivated due to an error: Plugin file does not exist. * Thread Starter [lilpenny1316](https://wordpress.org/support/users/lilpenny1316/) * (@lilpenny1316) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051255) * As a follow up: * 1. I deleted the plugin and reinstalled the previous version and activated it. 2. I then updated the plugin to the most recent version and as soon as the plugins page refreshed after the upgrade, I received that error message. * Plugin Author [unclhos](https://wordpress.org/support/users/unclhos/) * (@unclhos) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051262) * That is the expected error. You should be able to just activate the plugin now as if it were a new plugin. * Thread Starter [lilpenny1316](https://wordpress.org/support/users/lilpenny1316/) * (@lilpenny1316) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051269) * I tried this earlier and just tried it again and the page hung for five minutes and then gave me a 500 Internal Server Error. * Plugin Author [unclhos](https://wordpress.org/support/users/unclhos/) * (@unclhos) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051314) * If you want to email me a log in to take a look at it I will. Why did you install the old version again to update? Why not just install the new one? * Thread Starter [lilpenny1316](https://wordpress.org/support/users/lilpenny1316/) * (@lilpenny1316) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051337) * When I delete the plugin completely and install the new version, I get the 500 Internal Server Error. I cannot send a login because this is an organization website, but I’ll see if I can replicate this issue on a test server. * Thread Starter [lilpenny1316](https://wordpress.org/support/users/lilpenny1316/) * (@lilpenny1316) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051439) * I ended up re-installing the previous version of your plugin and activating it. Then downloaded your new version to my machine and renamed the PHP file to what it was previously and uploaded that. So it was the old file name with the updated coding. That worked. It’s not optimal, but had to get this working ASAP. I still do not know why the normal upgrade process timed out, but unfortunately cannot test it out right now. * [Jeff Sharpe](https://wordpress.org/support/users/jeffsustainablesummerorg/) * (@jeffsustainablesummerorg) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051451) * Same issue here. * Plugin Author [unclhos](https://wordpress.org/support/users/unclhos/) * (@unclhos) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051453) * Jeff, can you provide me a login to look at the issue? * [Jeff Sharpe](https://wordpress.org/support/users/jeffsustainablesummerorg/) * (@jeffsustainablesummerorg) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051455) * I just reverted back to the previous version for the time being. This is from the error log: * PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘[http://my.sustainablesummer.org’](http://my.sustainablesummer.org’); not found or invalid function name in /nas/content/live/summeralums/wp-includes/ plugin.php on line 235 * Anyway, I don’t personally need support (although thanks for the offer), but happy to help you troubleshoot for other users. * Plugin Author [unclhos](https://wordpress.org/support/users/unclhos/) * (@unclhos) * [10 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-on-plugin-update/#post-7051458) * From that error line, sounds like there is something wrong with the ajax filter I put in on line 122 of my plugin. But I don’t know what that would be, everything looks fine.
