Hi guys, I am encountering a few issues with this old version of OC. While trying to upgrade it to OC 4.0 and PHP 8.1, which was not successful, more errors popped up. I have since downgraded PHP to 5.3 which allows me access to my admin page again.

site: shop.mrsergul.com

1. Submission of cart, no response for customer but order comes through
2. Contact us page, no response, email does not come through
3. Multiple errors on admin page upon logging in and updating order status

Lastly, i read through the forum and enable display of errors (now deactivated) from PHP and this is what I see when I went to my site:
"Warning: mysqli::mysqli() [mysqli.mysqli]: Headers and client library minor version mismatch. Headers:100519 Library:100236 in /home/u422659863/domains/mrsergul.com/public_html/shop/system/library/db/mysqli.php on line 7"

Missing files...

Restore from backup and don't upgrade yet to 4.0.x....only to 3.0.3.8

@xxvirusxx, thank you! Do I restore just the OC backup or all the files in my File Manager too?

I'm checking with the host which PHP should work with my site. Thanks again!

I really wouldn't try something as involved as this unless you're an experienced developer.
