We are releasing a small fix for a bug we were made aware of with the video and mobi plugins in which an admin cannot add a video category when on mobile device. This patch is really just adding the admin file to three areas and does not require a full upgrade. You can fully upgrade your site if you wish though or if you are on a version below 4.10.3p2.
For manual fixing, just copy the
'admin-simple.tpl' file from /Applications/MAMP/htdocs/phpv4/application/modules/Core/layouts/scripts/
to
/Applications/MAMP/htdocs/phpv4/application/modules/Mobi/layouts/scripts/
/Applications/MAMP/htdocs/phpv4/application/modules/Core/views/scripts/
/Applications/MAMP/htdocs/phpv4/application/modules/Video/views/scripts/
and clear cache after.
