BBCode issue makes posts empty and appear only if code is disabled.

[EgyptWrite]

Hello, just mentioned additionally. STK - https://github.com/Tatiana5/phpBB3.2-STK
*More informations: https://www.phpbbguru.net/community/vie ... 64&t=42862

Important, therefore
please note that the STK is not a "toy". Always (!) create a DB backup beforehand.

BTW: Notes ...

Admin tools: This category contains tools for the administrator to maintain the board.

On the Fly: Test, try, take a look ...

Removing BBCodes: This allows you to remove incorrect or no longer desired BBCodes in forums and posts. Since the *STK (DEV) may be true, some functions may still work (perhaps) incorrectly, so please ALWAYS make a backup of the database before using it.

If necessary, test in a test board (branch). I don't know if there would be a translation for your required language. Just as it doesn't matter whether it leads/can lead to the result.

Hint: Without guarantee ...

Regards

Edit:
Mentally, I can't judge your case exactly in the history presented.

*) The Ext developers have to test their Ext´s with this PHP / phpBB version before they can release it.

Sorry for late reply, long journey with chemo. anyhow, I tried the STK yesterday and I could see it only remove the youtube/audio/video BBcodes , not all the codes. I need to remove everything and leave the text because that's the only way the issue can be solved. for example, in the attached screenshot, if I edit the post and removed all the bbocdes, the post will show perfectly, but without removing bbcodes, it's an empty post. and of course I can't edit every post and reply for the whole forum one by one :s

Any post with just <t></t> in the post_text column should be empty if you go to edit it normally through phpBB. How it would get to that state is anyone's guess.

If it's not empty on live forum then I'd double check you are looking at correct DB.
