Hello Jack,
thank you for the answer, i did modifications on files and i havn't more problems with theses files (test ok).
Now i have another problem:
I fill tags for title, description and keywords, then i clic preview, when i go back all the tags field are empty....
i'm not sure that it works??
For information i use ACA and TinyMCE too...
When i want to use advanced text editor for description i have the same matter than tags: all is empty when i go back (and the description isn't in advanced text)...
but tinyMCE appear to works: i can change pictures, with the title.......
I don't know if this problem comes from Tiny, ACA, or Header Tags Seo... for me the more important is that Header Tags Seo works (for search engine....).
Maybe you have an idear about this problem ?
Regards.
