For pre-checking reasons (before bying the Pro Version) I downloaded the free version to have a look how the plugin works.
Default setting is working ok and looks fine :-).
In the options I changed just the imange upload and tried to save, but this error appears:
503 Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
The same when I try to adjust something in CSS or .php and save.
I read through your FAQ, but did not find a solution. What's wrong? Kindly help.
Theme is Twenty Fourteen, Jetpack is also installed and some other plugins, but not many - those where I know they are reliable, like e.g. Shortcodes Ultimate.
Website is still under 'Comming soon' mode.
Hope you have an idea :-)!
P.S. Of course I checked with other plugins, all is working normal.
