Marcus, has your issue been resolved with the fix?

Thanks Ross that took care of the bug nicely.

I hope it will be included in the next update so that I wont have to patch it again :)

Great. Thanks for letting us know. 

Nicely done!

I'm actually having this issue. the tmp folder exists, perms 755.

my error.log has these lines in it, however

[Sun Feb 8 7:11:18 2015] [ow_core_log] [Notice] Message: Undefined index: HTTP_USER_AGENT File: /home/genderfl/public_html/genderfluidsocial.org/ow_core/request.php Line:158[Sun Feb 8 12:05:54 2015] [ow_core_log] [Exception] Message: Package pointer `ADMIN_WPCTRL` is not registered!

any thoughts?

additional: it doesn't seem to matter if i change to php 5.4 from the default 5.3 on the server.

Create a separate post with the issue as it has nothing to do with the topic.

Jordi, here's the fix: http://www.oxwall.org/forum/topic/29249?page=1#post-125338

However in your case, there's no 'undefined' message, it's just the spinning. While uploading avatar, please follow this tutorial: https://docs.oxwall.org/faq:parse-error-troubleshooting to find the error in your firebug console.
