Title: Error 500 Last modified: March 8, 2020 --- # Error 500 * Resolved [lucindalaverick](https://wordpress.org/support/users/lucindalaverick/) * (@lucindalaverick) * [6 years, 2 months ago](https://wordpress.org/support/topic/error-500-158/) * On the edit homepage page in the asset cleanup section, this error message appears: * > “The checked URL returned an error when fetching the assets via AJAX call. > This could be because of a firewall that is blocking the AJAX call, a redirect > loop or an error in the script that is retrieving the output which could be > due to an incompatibility between the plugin and the WordPress setup you are > using. > Here is the response from the call: Status Code Error: 500 * for more > information about client and server errors, check this link Suggestion: Select“ > WP Remote Post” as a method of retrieving the assets from the “Settings” page. > If that doesn’t fix the issue, just use “Manage in Front-end” option which > should always work and submit a ticket about your problem.” * I tried doing what the message suggested, I firstly changed the settings to “ WP Remote Post” and the following message appeared: * > “It looks like “WP Remote Post” method for retrieving assets via the Dashboard > is not working in this environment. > Since the server (from its IP) is making the call, it will not “behave” in > the same way as the “Direct” method, which could bypass for instance any authentication > request (you might use a staging website that is protected by login credentials). > Consider using “Direct” method. If that doesn’t work either, use the “Manage > in the Front-end” option (which should always work in any instance) and submit > a ticket regarding the problem you’re having. “ * I then changed the settings to manage in the front end and the following error message appeared: * > Note: The checked URL returned an error when fetching the assets via AJAX call. > This could be because of a firewall that is blocking the AJAX call, a redirect > loop or an error in the script that is retrieving the output which could be > due to an incompatibility between the plugin and the WordPress setup you are > using. > Here is the response from the call: > Status Code Error: 500 * for more information about client and server errors, > check this link > Suggestion: Select “WP Remote Post” as a method of retrieving > the assets from the “Settings” page.

It appeared around the time that I had to de-activate elementor, (I had some of the elementor scripts unloaded at the time of deactivation) and then I re-activated elementor. I have reset all of the asset-cleanup settings in the tools section but nothing seems to help! * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-500-158%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 15 replies - 1 through 15 (of 20 total) 1 [2](https://wordpress.org/support/topic/error-500-158/page/2/?output_format=md) [→](https://wordpress.org/support/topic/error-500-158/page/2/?output_format=md) * Plugin Author [Gabe Livan](https://wordpress.org/support/users/gabelivan/) * (@gabelivan) * [6 years, 2 months ago](https://wordpress.org/support/topic/error-500-158/#post-12521545) * [@lucindalaverick](https://wordpress.org/support/users/lucindalaverick/) thanks for reporting a potential bug and I’m sorry about this unpleasant experience! You have to check your server’s PHP errors log file. Check if you can get its path from “Tools” -> “Debugging”. Note that you didn’t have to reset all the plugin’s settings as this wouldn’t fix the 500 error you’re getting (I hope you had a backup via “Tools” -> “Export”). * You said: * > I then changed the settings to manage in the front end and the following error > message appeared: * Have you actually open a page in the front-end view (e.g. your homepage) and checked the bottom of the page to see if the CSS/JS management list is listed for you. It should be and it would take effect only for you (not your visitors). * If you can find out the latest PHP error logs from the error_log file, that would be great. You can strip any information you consider sensitive from the report( e.g. the full path to the PHP file). * [steltat](https://wordpress.org/support/users/steltat/) * (@steltat) * [6 years, 2 months ago](https://wordpress.org/support/topic/error-500-158/#post-12521565) * Same problem Here. When I update you plugin this happens. * Plugin Author [Gabe Livan](https://wordpress.org/support/users/gabelivan/) * (@gabelivan) * [6 years, 2 months ago](https://wordpress.org/support/topic/error-500-158/#post-12521574) * [@steltat](https://wordpress.org/support/users/steltat/) please check the errors you got in error_log. Can you see anything in “Tools” -> “Debugging”? An easier way would be to setup a plugin like “Error Log Monitor” which will report any errors you got. In my tests, I haven’t got any 500 errors. Are you also using Elementor? * Thread Starter [lucindalaverick](https://wordpress.org/support/users/lucindalaverick/) * (@lucindalaverick) * [6 years, 2 months ago](https://wordpress.org/support/topic/error-500-158/#post-12521596) * Thank you so much for such a speedy reply! Yes the CSS/JS management list is showing up on my homepage, I was just looking on the “edit page” sections before. * The last line (that mentions Ajax) of the php error log is: [03-Mar-2020 21: 49:28 UTC] PHP Fatal error: Out of memory (allocated 105381888) (tried to allocate 32768 bytes) …. includes/ajax-actions.php * Is this helpful? * Thank you, * Lucinda * Plugin Author [Gabe Livan](https://wordpress.org/support/users/gabelivan/) * (@gabelivan) * [6 years, 2 months ago](https://wordpress.org/support/topic/error-500-158/#post-12521601) * [@lucindalaverick](https://wordpress.org/support/users/lucindalaverick/) Hmm, I have a suspicion there’s not enough PHP memory to process the list because this latest version also pulls the hardcoded list so you can view it (although managing any of the non-enqueued assets is a feature available in the Pro version). Can you increase your memory? You might need to edit php.ini (or do it via a Control Panel from your hosting package). * Are there any other errors referencing to any Asset CleanUp file? * [davidpolanco](https://wordpress.org/support/users/davidpolanco/) * (@davidpolanco) * [6 years, 2 months ago](https://wordpress.org/support/topic/error-500-158/#post-12521831) * Hi Team, * I wanted to add that I bumped up memory from default 512M to 1024M and there was no resolve. * ``` Server architecture Linux 4.15.0-1040-gcp x86_64 Web server Apache PHP version 7.3.15-3+ubuntu18.04.1+deb.sury.org+1 (Supports 64bit values) PHP SAPI apache2handler PHP max input variables 10000 PHP time limit 3600 PHP memory limit 1024M Max input time 3600 Upload max filesize 50M PHP post max size 100M cURL version 7.58.0 OpenSSL/1.1.1d Is SUHOSIN installed?
