Hi, I posted the same question in Woothemes Forum with a little more information, http://forum.woothemes.com/topic.php?id=34830
Login is required so here is the post:
“Hi, I have probably the same problem but with Inspire. I have a fresh 2.1.3 together with Inspire, donwloaded Jan 8 2011. I have installed a clean EE on my localhost without problem.
But when creating a second project which should go with Inspire I get this error after the “license agreement” screen:
“An Error Was Encountered
Unable to load the requested language file: language/english/categories_lang.php”
I’m not sure _which_ folder the error is referring to but I noted the in /system/expressionengine/third_party/categories/language/english/ (these are the files from Inspire theme) there is a file named “lang.categories.php”
I did a quick test duplicating and renaming this file to “categories_lang.php” without success.
I have also search for the file “categories_lang.php” without success, both as physical file in the project and as text/string _in_ the files.
Do you have any ideas whats going on? Can it be something about permissions?”
