Memory Limit

Some users may experience a memory limit error. This means that your WordPress installation (core + theme + plugins) have overrun the memory limit allowed by your server. The error looks like this:

Fatal error: Allowed memory size of XXXXXXX bytes exhausted (tried to allocate XXXXX bytes) in /path/to/function/file on line XXX

Tip: You can check your PHP configuration settings by viewing the output of the phpinfo() function

The solution is to increase the PHP memory limit on your server. There are several potential ways to do this:

1. php.ini

Your server has a PHP initialization file (php.ini). To increase your memory, you change the memory_limit directive. Usually 64MB or 128M is a good amount.

memory_limit = 64M

The error message will indicate how many bytes (translate this to MB using Google if needed) your current system has allocated, and you can use this as a basis for how much you increase your limit.

2. wp-config.php

WordPress offers a way to Increase memory allocated to PHP in your wp-config.php file.

3. Contact your host

Depending on your host, you may or may not have access to php.ini, and they may disallow the wp-config.php solution. In that case, you will need to contact them directly to resolve the issue. If they refuse to increase your memory limit, you’ll either need to change your hosting plan or lighten your plugin/theme load to reduce the memory requirements of your installation.

Please note that this is not a problem with UberMenu – the available memory is shared among all plugins, theme, and WordPress core running in your installation. As the different parts of your installation load, they use up your server’s capacity. The error simply occurs on the function that happens to send it over the limit. Often the function that puts it over the top is only a few kilobytes.
