There are different causes for the Slider Revolution Ajax Error let’s list some of them:
- 1. PHP Memory Issue
- 2. PHP Version
- 3. Permission Issues
- 4. Old Version of Slider Revolution
PHP Memory Issue
This issue is caused by PHP UPLOAD MEMORY value.
In that case, the slider can’t be imported or opened because the memory allocated isn’t enough.
So to fix that you to edit the wp-config.php file and add these two lines of code:
define( 'WP_MEMORY_LIMIT', '256M' ); define( 'WP_MAX_MEMORY_LIMIT', '512M' );
If you have any host limit is impossible to change the Memory Limit. In that case, you have to contact your hosting provider or change the PHP LIMIT in the PHP.ini configuration file.
Sometimes this issue is caused by your PHP version. The latest version of Slider Revolution isn’t compatible with the older PHP version like PHP 5.x.
Change the PHP version by update it or change the hosting provider.
A wrong permission folder issue can cause all these problems with Slider Revolution and not only.
Change the folder permission through FTP or ssh. WordPress folder permission have to be 755
