We have now opened a commercial services section here on the forum for registered users. If you have a Fabrik project that you wish to have someone work on for you, post it under Help Wanted. If you are an application developer and wish to earn some money helping others, post your details under Fabrik Application Developers.
Both of these are unmoderated. It will be up to both parties to work out the details and come to an agreement.
For running J!5.1 you must https://fabrikar.com/forums/index.php?wiki/update-from-github/ or include the new file manually https://fabrikar.com/forums/index.php?threads/joomla-5-1-and-fabrik-cannot-find-files-error.54473/post-285151 See also Announcements
As often as you need a bugfix or a new features provided in GitHubUpdate from GitHub
Only if you want to install a new plugin.Go to Extensions > Extension Manager > Discover
Click 'Purge Cache' and then 'Discover'
Select your plugins and click 'Install'
Go to Extensions > Plug-in Manager

And whenever something isn't working correctly on your site, I've learned to NEVER post on the forum until you update from github first. It's fixed 50% of my issues. Hahaha.
PS - You post A LOT. Holy CRAP!!!!! (And I'm saying that in a nice calm voice, but rolling my eyes slightly).
