I have the same issue, i just found out. But only in the groups forum. I.e. if you go to the forum through a group.
If i go to the orca forum it self, then i dont have this issue.
This is what happens:
When I log in as admin, go to a group and post a new topic or a new post in the forum, everything works fine, in all browsers.
If I log in as a user on the other hand and do the same, the page will not reload after i hit the send button (after i have written a new topic for example) The topic is written though, its just not the page reload/redirect that works.
I use Charles Proxy to track this kind of issues and it tells me i get this response: <br /><b>checkAction()</b> fatal error. Unknown action ID: 0<br />
Logged in with the admin account i get this response for the same action:
<script language="javascript" type="text/javascript">
if (!1)
window.parent.alert ('Some or all files upload failed');
if (window.parent.document.getElementById('tinyEditor'))
window.parent.tinyMCE.execCommand('mceRemoveControl', false, 'tinyEditor');
window.parent.document.f.selectTopic('ggggggggggggg');
</script>
This checkAction function is located in forum/integrations/base/callback.php
I have no idea how to fix this or what is causing it, but if anyone recognizes the issue please let me/us know or if you need more information.
I'm using Dolphin 7.0.9
