Since I upgraded the theme-check plugin I receive this for one specific theme:
Fatal error: Maximum execution time of 30 seconds exceeded in /Applications/MAMP/htdocs/develop/trunk/develop/wp-content/plugins/theme-check/checks/i18n.php on line 27
When I keep debug on true i get 'undefined index' for that same line - >
I commented the last line in that file, so that the code would not execute, and it all works fine now. But what does that I18NCheck checks for? something about language?
