Hi @adesh1414127033 ,

I have got this error in codoforum v3.5.

Go to

http://codologic.com/forum/index.php?u=/category/codoforum-related-discussions

and click to the Create new Topic textarea. After create a topic, I can not post it. It says

CODOF.datepicker is undefined

I have to go back to the Add new Topic button to create new topic.

For this forum, v3.5.1, you wil get this error

<br />
<b>Notice</b>: Undefined index: is_auto_close in <b>/usr/share/nginx/html/forum/sys/Controller/Ajax/forum/topic.php</b> on line <b>281</b><br />
{"tid":"7190"}

I compared these files. I think we miss some CODOFVAR variables in the category.tpl

sites\default\themes\default\templates\forum\category.tpl
sites\default\themes\default\templates\forum\new_topic.tpl

Its working for us. Can you try deleting your cache ?

Yes, we noticed this, its a silly mistake on our part
