I'm glad your mbstring issue is over.
Looks like it popped up for me !! (I am not sure it is new because I haven't PHPMyadmin'ed for a while.)
My settings are
lPHPMyadmin anguage French (fr-utf(8)
Mysql charset (utf8-general-ci)
Mysql connection collation UTF-8 Unicode (utf8)
Re tables which contain text (articles), the collation is latin1-swedish-ci, except for one field (varchar) which is latin1-bin for whatever reason ???
As you know, we have a lot of accents in French but apart from the red warning when entering PHPMyadmin, accents look alright ... as far as I can see since I can't tell about BLOBs with PHP Myadmin.
Anyway, the red flag is pretty disturbing.....
Thanks for any enlightements.
Sorry for my English which looks sometimes ... strange.
