Hi Rouslan,
Just spotted the below error when clicking on "Create Version" after
selecting the "Tracking" tab at table level.
Fatal error: Call to undefined function PMA_getPlugin() in /home/www/pma/libraries/Tracker.class.php on line 270
Yes, I'm also getting this error. But if you can see, PMA_getPlugin() function is already exist in libraries/plugin_interface.lib.php file. The error is due to not include that file before calling that function.
I'm surprised that you didn't grep for every function that you have renamed to ensure that there are no more occurrences of the old function names before merging with upstream o_O
I have renamed the functions inside common.lib.php and now that file is appeared as CommonFunctions.class.php . Seems you have misunderstood.
Regards !
