 * Hello guys!
 * I had updated to last Yoast SEO version, when it was launched, but now I had 
   a check into the latest web server error log messages.
 * I have many errors like this:** [lsapi:error] [pid 25392:tid 47500726859520] [
   client ###.###.###] Backend fatal error: PHP Fatal error: Allowed memory size
   of 536870912 bytes exhausted (tried to allocate 77824 bytes) in /home/#/public_html/
   wp-content/plugins/wordpress-seo-premium/vendor/composer/ClassLoader.php on line
   478\n, referer: /#pages.**
 * I have many features disabled because I don’t want to bloat the admin page, I
   raised the allowed memory as the error describe, should be enogh, but still fatal
   error, too many resources wanted by the plugin. Any advice?
 * Many thanks!

 * Hi [@cls350](https://wordpress.org/support/users/cls350/)
 * Based on the error message, this error occurs when your server runs out of memory
   to complete the task at hand.
 * You’ll need to either increase the memory or decrease the number of tasks.
 * You can learn more about it here – [https://yoast.com/help/common-installation-update-errors/#memory-exhausted](https://yoast.com/help/common-installation-update-errors/#memory-exhausted)

 * Hello Michael Tina!
 * Unfortunately, I have allocated 512 MB, as the error said: 536870912 bytes (are
   512 MB) and was not enough for Yoast Plugin.
 * Many thanks!

 * You’ve increased the memory limit but the problem exists. Please keep in mind
   that the required memory for your site depends on your content, theme, and all
   plugins.
 * Note: If this solution does not work for you, then this means your web hosting
   service provider does not allow WordPress to increase PHP memory limit. You will
   need to ask your web hosting provider to increase your PHP memory limit manually.
