5. Create new topic or reply to existing topic

To be tested
I had one testsite where the problem resolved itself?? But unfortunately can't reproduce what I did.

Then in new J523 site problem occured again.

Go back to topic and attachment is nicely inserted in message.

I get the error even if I don't attach any images.
It might have something to do with this bug. #9799
Because when I use the following setting, the error message is gone. (But with this setting you can't upload attachments.)

1. set in the configuration (tab) Security - Prevent that new users are able to add url and image in his messages or profile
2. set a higher number as user has posts to able to add url and image

I get the error even if I don't attach any images.

Confirmed. I was so focussed on attachments that I forgot to test only text.

Can confirm the empty [img][/img] tags as well.
We don't use it frequently in our forum, most images are attachments, but mods have a donationbutton in their signature and there I can reproduce it.

K 6.3.8

K 6.4.0

Don't look at the color difference. Live site is with 9themestore template and custom css, testsite with Aurelia, to make sure there are no template conflicts.

I don't see any connection between the last line in the call stack and the error message after saving.

I'm not a programmer, but I'm curious and so I compared the KunenaAccess.php file in version 6.3.8 with the one in version 6.4.0-RC2.

Maybe that can help with the solution.

In 6.4., line 20 is missing

6.4 is missing lines 127 to 141

6.4 line 161: $query = $db->createQuery()

6.3.8 line 177: $query = $db->getQuery(true)

6.4 is missing lines 188 to 206

6.4 line 272 and 6.3.8 line 307 a quotation mark is missing or there is one too many:

“function kShowAccessType(htmlclass, el) {

6.4 line 796: $query = $db->createQuery()
