Question Publishing posts extreamly slow - Kunena 4.0.11

I think its a plugin issue.

Try to backup all plugins files, then remove the files on the server, then extract the plugin files from joomla package. then install kunena again.

Then try to post a message again.

I hate to seem dumb but do you mean all Kunena plugins or all Joomla plugins? I only use 3 Kunena plugins (listed below) but there are dozens of Joomla plugins that came with the original installation. I'm not a professional developer so please excuse my ignorance when it comes to deleting all the plugins and reinstalling them.

1. Kunena - UddeIM Integration
2. Kunena - Kunena Integration
3. Kunena - Joomla Integration

you mean all Kunena plugins or all Joomla plugins?

No, disable the plugins of your extensions. As example your jce media box.

I meant, remove all files manually.
So make first a backup of that files. Then extract the plugins dir from the joomla package, then install kunena again.

Then try it.

If it works, then restore the plugins dir, 1 by 1, until the one is broken

Thanks for your help. I'll give that a try.

I've not had time to so as you suggested with the plugins but I just discovered that once a post has been made, editing it and then saving it takes less than 5 seconds like you would expect. It's odd that it takes 15-30 seconds to save the same post for the first time. Does that possibly give a hint about what is going on?
Thanks!
