Hi Ronan,
Thank you for buying Pimp My Site! We hope it will meet all your expectations! 🙂
Can you please tell us which browser app you’re using on mobile? We tested on safari, but all is working fine.
The fact that you face this issue now on desktop too might not be related. To help us getting clues and find a solution to this issue, please activate logging on your website, just turn WP_DEBUG to true, by pasting the following code lines in your wp-config.php file, just before the line that says ‘That’s all, stop editing! Happy blogging.’:
// Enable WP_DEBUG mode
define( 'WP_DEBUG', true );
// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );
// Disable display of errors and warnings
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );
More on this in the following topic: Debugging in WordPress.
Thank you.
