I agree, it should not take longer than 30 seconds to save a category. In fact, it should not take longer than a couple of seconds max.
Does anybody not using IPS Hosting have these issues?
Unfortunately, I have found that IPS Hosting is a shared server environment that does not meet certain requirements for the GC app. It is configured specifically to meets the needs of IPS core, which is great, but as soon as you step outside of those operating parameters then it becomes problematic and rigid.
For example, the category configuration form for GC typically contains more form elements than the configuration of IPS servers will allow to be submitted at one time. Most servers support this without a configuration change, but occasionally a server will have its limits set too low for GC.
Usually you can make the configuration change yourself or ask your host to loosen things up which will solve many problems. IPS cloud community however is not one of those where the configuration can be customized.
Because of this, I'm not sure what can really be done to rectify the problem.
With that said, if you want to go ahead and PM me with details for your site, l'll have a look at it to see if there is anything I can do.
