LOL, yeah right, I don't know anything about coding
Show us the difference in the front controller then.
You are the fool here. You would be much smarter if you kept quiet and try to dodge this one under the radar.
ALL the files in your upload have the same date/time of modification as version 2.4.9
The only one that differ in modification date is 'ets_seo.php'. And that is modified 2022-08-24.
Version 2.5.2 was released 2022-08-17. So that's kind of a mismatch.
When comparing the file 'ets_seo.php' in your uploaded module from the version 2.4.9 there is only one line that differs. You have changed line 92 from
PHP:
$this->version = '2.4.9';
to
PHP:
$this->version = '2.5.2';
And of course I compared all the files in your upload to version 2.4.9. I didn't only look at the modification date.
Your uploaded zip contains the folder __MACOSX. So the module has been re-packed/re-zipped on a MAC. If you didn't even bother to remove the module_key there is no reason to repack a module.
