The errors are about being unable to open files with the only helpful hint being that there are some memory errors listed. * I believe the issue is caused by a combination of two things. First, your PHP memory limit is set too low. Second, something on your site (either your theme or other plugins) is using up all of your available PHP memory. * Think of PHP memory as RAM for your computer. You can only run so many programs at a time. * What I think is happening is that your PHP memory has run out which means there is no more “memroy” left to load HD Quiz (which is a SUPER small and lightweight plugin BTW). This is why you are seeing errors about not being able to load in files. * **How to fix?** First thing is to increase your PHP memory. The way to do this will vary depending on your host and setup, but usually, the easiest way is to edit your `wp-config.php` file found in the WordPress installation folder. Here is a good article I found that goes over how to do this: [https://docs.wp-rocket.me/article/128-increase-php-memory-limit-in-wordpress](https://docs.wp-rocket.me/article/128-increase-php-memory-limit-in-wordpress) * Once you have done this, the next thing to do is try and determine why you were running out of memory to begin with! I recommend deactivating any plugins you don’t actually need or use, or even try switching to a “lighter” theme. * Thread Starter [theavengers](https://wordpress.org/support/users/theavengers/) * (@theavengers) * [3 years, 10 months ago](https://wordpress.org/support/topic/php-fatal-error-305/#post-15755959) * Hello, i have 512Mo, but i think i have found issue.
