# Memory error causing error 500

 * Hello,
 * I wonder if you can help, basically this morning this plugin sadly took one of
   our websites down, the error it hit was:
 * E_ERROR was caused in line 72 of the file /home/web/public_html/wp-content/plugins/
   really-simple-ssl/rlrsssl-really-simple-ssl.php. Error message: Allowed memory
   size of 1073741824 bytes exhausted (tried to allocate 18330720936 bytes)
 * We reported this to our hosting company and they confirmed: It tried to allocate
   around 17gb or memory which is excessively high. Your limit is just 1GB which
   should be more than enough.
 * On investigation it seems to crash in a rather general function from what we 
   can see: [_self::$instance->front\_end = new rsssl\_front\_end();_](https://cpanel2-realityhouse.dedicated.catalyst2.com/)
 * For now we have left the plugin off, but would really appreciate any help in 
   terms of understanding any specific cause for this and how we can avoid it moving
   forward.
 * Many thanks for your help,
   Tonya

 * Hi [@tjldesigns](https://wordpress.org/support/users/tjldesigns/),
 * it’s hard to say what’s causing this issue exactly, as there’s nothing in the
   rsssl_front_end class that could cause so much memory usage. It’s likely that
   something else is using a lot of memory, but the warning is only triggered when
   the rsssl_front_end class is loaded. To further debug this issue, you can take
   the following steps:
    1. Enable debugging in WordPress by adding the following lines to your wp-config.
       php file:
       define(‘WP_DEBUG’, true);define(‘WP_DEBUG_LOG’, true);This will write
       any additional errors to a debug.log file in your /wp-content folder.
    2. Use a plugin like Query Monitor which provides detailed insights into memory
       usage, which can give more information as to what function is causing this specific
       issue on your site.
 * If you can check provide us with a debug.log when the issue occurs again and 
   check what happens in Query Monitor when using the plugin we can help you identify
   the issue.

 * [@tjldesigns](https://wordpress.org/support/users/tjldesigns/) as you can see
   here:
    [https://plugintests.com/plugins/wporg/really-simple-ssl/latest](https://plugintests.com/plugins/wporg/really-simple-ssl/latest)
 * The plugin takes about 100kb in memory.
 * That the error comes from Really Simple SSL doesn’t mean it is caused by it. 
   It just throws this error when the memory limit is reached. The cause can be 
   somewhere else entirely.
 * If you actually see a **big** memory decrease with the plugin disabled (a 100kb
   decrease could also lower the memory usage to just below the threshold), it might
   be a plugin conflict with another plugin. We’d need to know what plugin that 
   is to be able to investigate.
 * You can check this by disabling all your plugins, switch to a default theme, 
   then activate Really Simple SSL, then activate the other plugins one by one until
   the issue returns.
 * If you know which plugin or theme is causing the issue we can investigate further.
