why all posts are lowercase

[maaref]

any post contains uppercase either complete word or a letter it turns to lowercase.

In the editor it remains no change even after save.
the problem is in the post.

How I can solve this.

appreciate any assistance.

In the settings in the adminCP, try going to the "Message Posting and Editing Options" and look for the Prevent 'SHOUTING' setting.

Hi kh99
It is disabled.
I enable it and disable it no change.

Try disabling your modifications/plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit includes/config.php and add this line right under <?php

define('DISABLE_HOOKS', true);

Thank you very much
I found it
thanks for your advice.

the problem was due to Word Replacements (https://vborg.vbsupport.ru/showthread.php?t=93758&highlight=Word+Replacements)

this is an old plugin causing any uppercase text to be lowercase in post in my forum
I remove it and evrything now is excellent.

I put the link so if anyone have same problem or similar one can do same process.

best regards,
