Multilingualism of the site ru/ua to be fixed

Budget: 4500 UAH Deadline: 2 days

Aristarch, good day!
Most likely, some configuration has failed, and a couple of files are missing, as it was on this project I worked on https://t-h-logistics.com/
I see that you have quite an old version of OpenCart; have you considered upgrading to 4.0? Just on 2.3, there are a lot of vulnerabilities through which the site can be broken.
I can approach the task comprehensively; localization will work, each page will have a 200 response code, + I will update the site to the latest version.

Good day.

I understood the task: OpenCart 2.3, after cleanups the language switching broke — the prefix `/ua/` disappears, slow loading when switching, Google is already detecting errors and has started removing it from search results.

Based on the symptoms, there are three possible reasons: the vqmod/ocmod module for language URLs has failed, the SEO URL settings in the config have been messed up, or the rules in `.htaccess` have been corrupted. Additionally, it will be necessary to restore the `hreflang` tags and update the sitemap in Google Search Console — otherwise, the rankings will continue to drop.

Three questions before starting:
1. How is the multilingual setup done — standard OpenCart or a third-party plugin/module (if you remember the name)?
2. Is there a backup before the attack (at least partial)?
3. Is there access to Google Search Console — to check specific errors from Google?
Send the website in a private message — I will take a look from the outside and provide an exact price. Since the site has already been attacked once, I can also check for basic security holes in parallel — this won't add to the timeline but will help prevent a recurrence.

Hello! I have fixed multilingual issues on OpenCart 2.3 multiple times — usually after removing a module, the SEF/language link connection breaks, which causes the missing ua prefix, slow switching, and errors in Google. Please send the website and access to the admin panel/FTP — I will check what exactly the admin removed and restore the correct switching between ru/ua without losing positions. I think I can manage it in a day. One question: is there a backup of the website (or at least the database) before the issue occurred?

Hello, I am ready to restore the proper functioning of the ru/ua versions of the website.

Hello.
It's better not to delay with such issues because if the search engine already sees broken links and duplicate pages, the rankings may continue to drop.
I once had a similar case after an unsuccessful cleanup of modules on OpenCart; the site appeared to work fine, but search engines began to find errors in the language URLs en masse.
Can you send the website and access to the list of errors from Google Search Console, if available? After that, it will be clear whether the problem lies in the language module, SEO URL, or settings after the attack. Also, please let me know if changes were made only after the attack or if something was updated on the site before that as well?
