Website audit

▎ Good day! You have localized the issues well — even naming the conflicting files and the error line, so this is targeted debugging, not "digging blindly." I will proceed as follows:
▎
▎ 1. Error 500 when updating modifiers — seo_package.ocmod.xml and unixml.ocmod.xml are most likely modifying the same node, and OCMOD fails during recompilation. I will find the overlapping operation and make a targeted fix (order/selector) so that the modules coexist ▎ — without interfering with the SEO settings, as you requested. The "Update" button will work.
▎ 2. Console (F12) — I will remove calls to parallax.js and addthis, and fix the TypeError in custom.js:395 (sitManParallax is most likely a reference to an element that no longer exists after removing parallax).
▎ 3. Category layout — I will correct the display of elements.
▎ 4. Security — I will review files for suspicious inserts (both files and typical injection points), not just superficially.
▎
▎ Before starting — a complete backup of files and the database through the hosting panel, as per your conditions. Fixed price for the result — I agree.
▎
… ▎ Question: can you provide access to the admin panel + a list of modifications (Modifications) so I can confirm the cause of the conflict?

Familiar stack - ocStore/OpenCart 3, ocmod conflicts, JS errors. All 4 points are clear, the task is straightforward. The conflict between seo_package and unixml is a typical issue with overlapping xpath patches, resolved by targeted editing without affecting the logic of the modules. JS errors and layout - standard cosmetic issues. Backup before starting - mandatory, I agree with your condition. Ready to take it on.

Hello. I will perform a technical diagnosis of your project, resolve the conflict between the modules causing the 500 error, and fix the layout display. I will also clean the console of outdated scripts and correct errors in the style files, first making a complete backup of the system. Optimal budget: $90 – $120 (approximately 3700 – 5000 UAH). We will create a technical specification and discuss the deadlines for each item. Backups and ready to go. If this approach suits you, let's discuss the details in private messages.

Estimated cost of work (Fixed budget)
1. Error removal 500 (Conflict between SEO Package and UniXML):
- What is done: Log analysis, searching for tags in two .xml files, removing overlap. Price: $25 – $40 (approx. 1000 – 1600 UAH).
2. Console cleanup and fixing custom.js:
- What is done: Removing script connections in header.twig/footer.twig, adding an if condition in JS to isolate TypeError.
Price: $15 – $25 (approx. 600 – 1000 UAH).
3. Layout correction in categories:
- What is done: Aligning product cards via CSS (Flexbox/Grid) so that titles or buttons do not shift.
Price: $15 – $30 (approx. 600 – 1200 UAH), depending on the number of responsive screens (mobile/PC).
… 4. Cosmetic check (Express audit for viruses):
- What is done: Searching the file signature database for eval, base64_decode, checking file modification dates via SSH/FTP.
Price: $15 – $25 (approx. 600 – 1000 UAH).
Total summary:
1. Minimum budget: $60 – $80 (about 2500 – 3300 UAH). We start immediately, without a technical task, discussing the task list, backups, and getting to work.
2. Optimal budget: $90 – $120 (about 3700 – 5000 UAH). We create a technical task, discuss deadlines for each item. Backups and then to work.

Hello!

I have experience with ocStore/OpenCart 3, OCMOD conflicts, and point adjustments of modules without unnecessary interference in SEO settings. I can create a backup, find the cause of the 500 error when updating modifiers, remove errors in the console, and check for suspicious inserts in the code.

Hello!

The task is completely clear, and I am very familiar with the logic and architecture of OpenCart 3 (ocStore). I work exclusively for results at a fixed price, without any hourly counters. The condition for a mandatory full backup (files + database dump) before starting any manipulations is a strict rule of my work.

I am ready to perform localization and resolve all the mentioned technical issues. Here’s how the work will be implemented:

1. Fixing the 500 error (Modifier conflict):
There is no need to reconfigure or touch the business logic of Complete SEO Package or UniXML. I will analyze the modification cache in system/storage/modification/, find the controller or model method where the XML instructions of both modules attempt to make a replacement (search/replace) in one place, and I will make a precise engineering fix in one of the files (.ocmod.xml) so that they are applied correctly in sequence. The "Update" button will work as intended.

… 2. Console cleanup (F12) and frontend:
• I will remove outdated and irrelevant script calls (parallax.js, addthis) from the templates (header/footer) to eliminate unnecessary 404 requests and speed up page loading.
• In custom.js (line 395) in the sitManParallax function, I will add a check for the existence of the object in the DOM (isolating the call from TypeError) so that the script does not fail on those pages where the parallax element is physically absent.
• I will correctly adjust the display of elements in product categories according to your wishes.

3. Security (Cosmetic audit):
I will scan critical system directories, configuration files (config.php, index.php, folders system/ and catalog/) for hidden redirects, external code injections, base64 inserts, or remnants of malicious scripts left by previous developers.

Development conditions:
I will perform the work on a copy of the site or directly on the "live" server only during night/non-working hours (after creating a backup) so that it does not affect current orders and the work of managers.

• Fixed price for the entire pool of work: 3,500 UAH.
• Completion time: 1-2 days from the moment of receiving access.

I am ready to start today. I look forward to chatting with you to discuss the details and transfer access (FTP/SSH and OC admin).
