Title: Error 500 without modification Last modified: November 7, 2020 --- # Error 500 without modification * Resolved [Manuel Vita](https://wordpress.org/support/users/manuelvita96/) * (@manuelvita96) * [5 years, 7 months ago](https://wordpress.org/support/topic/error-500-without-modification/) * Hi, I have installed some months ago Hummingbird (the free version), I have always update to the latest version. Today I have recived a notification that my site is down. I have checked immediatly and see the 500 error. I can’t even open the dashboard so I have deleted Hummingbird plugin folder and the website is up now. The error log show hundreds message like this: PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 98304 bytes) in /home/***/ public_html/***/wp-includes/wp-db.php on line 1999 This error happened from days, but only today the plugin stop working. I have tried to reinstall again but I have the same error again and again. Nobody make changes on the website before the down.

Both sites are incredibly slow sometimes and checking resources they use a lot of Physical Memory. I think that last update broken everything because until past week there is no problem and the speed was great. * Edit: I have tried to empty all caches on the other two website and Cloudflare return the error 524.

Just to be sure could we know how did you try increasing the memory? Sometimes the server doesn’t reflect the changes made via php.ini file. * Could you please create a file called info.php in the root directory and add the following code: `` * Once added, you can call the above info.php file in the browser via: abc.com/ info.php * Where abc.com is supposed to be the URL of your website. Where you can check the value which is assigned for the term “memory_limit”. * The above helps with figuring out the memory_limit of your server and to see whether the changes added to set 2048M actually got reflected or not. * This should help in moving forward. Looking forward to your response. * Kind Regards, Nithin * Plugin Support [Patrick – WPMU DEV Support](https://wordpress.org/support/users/wpmudevsupport12/) * (@wpmudevsupport12) * [5 years, 6 months ago](https://wordpress.org/support/topic/error-500-without-modification/#post-13742912) * Hi [@manuelvita96](https://wordpress.org/support/users/manuelvita96/) * I hope you are doing well. * We haven’t heard from you in a while, I’ll go and mark this thread as resolved. * However, feel free to let us know if you have any additional question or problem. * Best Regards Patrick Freitas Viewing 12 replies - 1 through 12 (of 12 total) The topic ‘Error 500 without modification’ is closed to new replies. * ![](https://ps.w.org/hummingbird-performance/assets/icon-256x256.gif?rev=2633221) * [Hummingbird Performance - Cache & Page Speed Optimization for Core Web Vitals | Critical CSS | Minify CSS | Defer CSS Javascript | CDN](https://wordpress.org/plugins/hummingbird-performance/) * [Frequently Asked Questions](https://wordpress.org/plugins/hummingbird-performance/#faq) * [Support Threads](https://wordpress.org/support/plugin/hummingbird-performance/) * [Active Topics](https://wordpress.org/support/plugin/hummingbird-performance/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/hummingbird-performance/unresolved/) * [Reviews](https://wordpress.org/support/plugin/hummingbird-performance/reviews/) * 12 replies * 4 participants * Last reply from: [Patrick – WPMU DEV Support](https://wordpress.org/support/users/wpmudevsupport12/) * Last activity: [5 years, 6 months ago](https://wordpress.org/support/topic/error-500-without-modification/#post-13742912) * Status: resolved
