Hello,

Our kunena forum has been migrated some weeks ago from Joomla 3 to 4 and we are now using latest version of kunena.

joomla: 4.3.2
kunena: 6.1.1
template/theme with gantry5 / helium

Some user are not able to post replies and they have following error displayed on their side:

"0 Unsupported operand types: string + string"

I'm not able on myside to reproduce the issue.

In webserver logs I can see a 500 response code on POST https://FQDN/

Enabling some debug on joomla I get this stack (I'm obfuscated the IP address)

Code:
2023-07-05T12:52:41+00:00       CRITICAL        error   Uncaught Throwable of type TypeError thrown with message "Unsupported operand types: string + string".

kunena debug mode is not showing info (I guess this is only available for admin account ?)

Happy to give you more context / info.

Adding some info,

I've looked into the code and debug a bit the issue.

The error appears in (), near line 1422, there is a SQL that do:
select MAX(time) from kunena_messages where ip='USER_IP';

where USER_IP is a parameter,

It looks like the result is malformated and is not a date in some cases.

I notice that in the table the ip column can have NULL in some cases.

Also, I was wondering if the following code is supposed to be ok if we don't find the IP, $lastPostTime is NULL in this case ?
Code:
if ($lastPostTime + $config->floodProtection > Factory::getDate()->toUnix()) {                 throw new Exception(Text::sprintf('COM_KUNENA_LIB_MESSAGE_ERROR_FLOOD', (int) $config->floodProtection));                 return false;             }

any insigt from the dev team ?

Is it a joomla migration 3 => 4 (or following kunena update) that were not OK ?

Should I fix account in the table ?

Hello,

I haven't looked yet at this issue, if you modify directly in the table the issue could come an another time with others users
I don't provide support by PM, because this can be useful for someone else.

thx for your feedback, I'll wait for a deeper analyse, current status is that without flood protection it is ok.

I can provide you with some data from DB if needed

Same problem on my website which was migrated to Joomla 4 and Kunena 6 last year.
Has been working fine until Kunena 6.1.1 and then Registered users started reporting issues replying to posts.
Super Users are not affected by this problem.

Submitting a Reply in "Private message" works just fine but not in standard "Message". "Thank you" features and "Polls" work too.
Strangely, if a registered user posts a "Private message" and then edits it to become a standard "Message", the post is saved correctly.

Disabling flood protection in the Kunena config removes the problem as reported by oxygen77 (Thanks for that tip) but setting it to a high value does not resolve the issue
