Unchecked all words in the Filename section (Ctrl-N ), but still get the same error.
It would also be to great help if the error message could specify which string(s) that matches.
Please let me know if this helps. If not, I would need exact Project settings (select it, Ctrl+C and paste to the message) and the URL that gets rejected.
This might be a possible explanation as the page in question is dynamic, with URL ending f. ex. with &inLayout=0
But I thought this would work as long as php is added to the allowed extensions, at least it does at another site which have FURL's.
And I do have PHP added to the File Filters/Text (And checked) for the profile in question.
