Yeah ! Now I see the about box !

I see a blank white page.

No, it doesn’t display.

No, It has exactly my first post display:
https://upcity.ir/images2/68295112388008491911.png

But other pages have boxes:
wps_browsers_menu
wps_countries_menu
and …

Thanks but I replaced that file and problem not solved.

Memory usage in PHP: 71,505,648 Byte
PHP Memory Limit: 256M

I upgraded from 8.0 to 8.1 . Problem still exist.
Yes, all files are there but the sizes have this differences:
jqv.map.php 4.36k
countries.php 2.29k
hits.php 3.88k

I did but I don’t see “about box”

I sent you.

I disabled all plugins and I still have that problem ??

Yes, I use “wp-jalali”. I deactivated that but I have that problem.

In log.php file (wp_statistics/includes/log) I see exactly that code in beginning of file:

<script type=”text/javascript”>
jQuery(document).ready(function(){
postboxes.add_postbox_toggles(pagenow);
});
</script>

I wanted host provider and they said I must put “php_flag display_errors On” in htaccess file. I did that but I don’t see any error.

How can I see server’s PHP error log?

Yes, manual/settings/optimization pages work.

In page source, after this code I don’t see anything:
<script type=”text/javascript”>
jQuery(document).ready(function(){
postboxes.add_postbox_toggles(pagenow);
});
</script>
and finished at this.
and it don’t have any “fatal error”.
