If you’re experiencing issues with saving your map settings, the most common reason is that your server configurations are limited.
To fix this problem, you must increase the server’s PHP.ini values to allow for the saving of longer settings or larger data. Edit the PHP.ini file and increase the following values:
For example, if you want to increase the memory limit to 256MB, locate the following line in php.ini:
memory_limit = 128M
Change it to:
memory_limit = 256M
Save the file.
Please note that changing PHP configuration settings should be done with caution, especially on shared hosting environments. Increasing memory_limit or other values too much can consume more server resources and may lead to performance issues.
Also, some hosting providers may not allow you to modify php.ini directly, in which case you might need to contact your hosting support to make these changes for you.
