I have been experiencing a timeout and have just diagnosed it as being caused by Smartcrawl Pro.
All I do is go to WPAdmin->Appearance->Menus and try to edit a label of a menu item. When I click save the page takes forever and times out. When I deactivate Smartcrawl and try the exact same process all works perfectly once again. Then activating Smartcrawl Pro once more causes the timeout to reappear.
Here is what is found in my cpanel error logs:
Timeout waiting for output from CGI script /path/public_html/wp-admin/nav-menus.php, referer: https://subdomain.my-network.com/wp-admin/nav-menus.php
Not sure if this error was present before or after the recent update, as I am new to Smartcrawl.
If it helps my host is SiteGround and SmartcrawlPro is setup on a subdomain WPMS installation.
Please address this bug asap.
