We had an issue reported with admin menus and have released a patch. Please download the SEPHP 5.2.0p1 upgrade file and upgrade the core again if you upgraded already. For fresh installs who hadn't installed yet, be sure you download the SocialEngine 5.2.0p1 file and install that.
The Changelog for this fix:
application/modules/Core/Api/Menus.php
I came to complain but , I see you are ahead.
Please don't post issues in the release threads as it takes it off topic. Also, test at the demo to see if you can join before posting another thread for the issue as I've not seen any issue for this when testing on staging. If you don't have an issue signing up at the demo, it is most likely a plugin related issue or something happened during the upgrade but you need to post a new thread please.
Our community is now updated to 5.2.0p1
sure , ok.
