Actually thats a different error than you posted above but means the same thing cause now its not finding your language file instead of the template
All these categories seem to be using an Ad Type which has an id of 5 which means we are looking for certain files
Code:
Content visible to verified customers only.
Do you see what I am talking about here. All those categories have the template setting in the categories table set to something higher than 0
This is the only way you can get those errors and is why I have been saying all along that you have tried defining an ad type with an ID of 5 and set these categories to use it.
There really is no other explanation here run this query and post the results here
SELECT template FROM pp_categories WHERE id=43;
