They are using Acymailing right now ( Newsletter in the Queue Process) — Saddly I cannot replicate the problem myself because I’m still running Mountain Lion, with an older version of safari that work without problem — I have to finish to big job before I update my system (a big 5 days job) if everything go well…
I will test the debug when the mailing will terminate, but not having the problem myself will probably not help me to find the problem.
The only server log error that the site generate and are under investigation is probably not related:
— PHP Notice: Use of undefined constant JPATH_COMPONENT_SITE - assumed 'JPATH_COMPONENT_SITE' in /home/zzzzzzzzzzzzzzzzzzzzzzzzz/public_html/modules/mod_languages/helper.php on line 67
