I don't have any language modules to unpublish.
Tried to update again and unpublished all plugins and modules that were related to CB or CB subs. Now have CB 2.0.12 running but still getting multiple instances of:
"Warning: Invalid argument supplied for foreach() in <span>/</span>home<span>/</span>l3dmarke/public_html/acbs/libraries/CBLib/CBLib/Language/CBTxt.php on line 518"
Have to scroll down the screen to get to "User Management" button etc. (see file attached)
The Debug Console flags a "Parsing Errors in Language Files"
JROOT/administrator/language/en-GB/en-GB.com_joodb.sys.ini : error(s) in line(s) 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 24, 26
SOLVED: the en-GB plugin was missing. Downloaded the plugin and published it and the error message went away.
