A breach has been detected on the active online store. After manually removing an unknown user with administrator rights, they are automatically recreated after a certain period. This indicates the presence of an active backdoor or hidden shell in the site's files or database. Task for the performer: Isolation and removal of the backdoor: Find and eliminate the script that generates fake administrators (audit functions.php, the mu-plugins folder, the database, and scheduled Cron jobs). Comprehensive scanning: Check all core files, plugins, active theme, and database for other malicious codes, spam links, hidden redirects, or trojans. Cleaning and restoration: Remove all detected viruses and unauthorized accounts. Reinstall core WordPress files with clean versions without damaging the product database and store settings. Correctly update the core to the latest version and update all plugins. Basic protection: Configure a security plugin (e.g., Wordfence or similar), change salts in wp-config.php, and provide instructions for changing passwords for the database and hosting. Candidate requirements: Practical experience in cleaning WordPress sites from viruses (at least 2 years). Understanding of how malicious scripts work (WP-VCD, backdoors, shells). Ability to perform manual cleaning, not just rely on automated scanners. Availability of feedback on successful completion of similar tasks. Expected result: A completely clean site that operates stably. Unauthorized administrator users do not reappear after their removal. A brief report on the completed work is provided (where the malicious code was found).

It is necessary to refine or adjust the import from the link of the donor site. The donor site is located on Prom.ua, so there are no issues with the link. The site to which the import will go is kamilla-ua.com CMS - Opencart 2.1.0.2 Number of products - several thousand. Currently, there is some broken or custom module installed that does not work correctly https://ibb.co/7dBnVTYj, it hangs during import and shows a 500 error. What we would like to see: 1. Import status (in % or in the number of products, to understand whether it has hung or is actually progressing) 2. Multithreading or another optimization option during import (so that the site and/or server does not crash after pressing the "import" button) 3. Saved current settings, the ability to update products/categories without overwriting. 4. Multilingualism (import into Russian and Ukrainian separately or any other combination) Considering that it is not entirely clear how long this may take, please provide your rate and estimated number of hours if you were to take on this task from scratch (installation, configuration, testing of the relevant functionality). This is not the only task, further development of multilingualism and correct translation is also planned. Proposals to create a new site will be automatically rejected. Unfortunately, the budget is not sufficient at this time.

I'm looking for an experienced Full-Stack developer (PHP, JavaScript/jQuery, HTML5, CSS3) to make a pool of small but important adjustments on an active website. The site runs on a clean PHP/MySQL stack without heavy CMS, so it's important to be able to read and carefully edit someone else's code.What specifically needs to be done: Footer adjustment: Completely remove the display of the first level of the product catalog (categories) from the bottom menu of the site. Main menu adjustment: Remove all links to informational/text pages from the top (main) menu. Moving text pages: Move the specified text pages (“About the Company”, “Our Partners”, “Our Projects”, “Order Installation”, “Payment and Delivery”, “Privacy Policy”, “News”, “Contacts”) to the bottom of the site (in the footer) — to the place where the upper levels of the product catalog were previously displayed. Contacts and social networks: Display the current phone number (make it clickable for mobile href="tel:") and social media/messenger icons in the header and footer of the site. Consultation order functionality: Button in the header: Add a neat, stylish button to the upper header of the site on the right (next to or below the phone numbers). Text on the button: “Engineer Consultation”. Button design: Execute in a minimalist style using brand colors, add a small phone receiver icon to the left of the text and round the corners (4–6px). Be sure to set up an interactive hover effect when hovering the mouse. Modal window (jQuery/JS): When clicking the button, a pop-up window with a form (Fields: “Your Name”, “Phone Number”) should open. Backend (PHP): Data from the form must undergo basic validation for correct input, spam protection, and be instantly sent via PHP mailer to the company's email. Requirements for the result: Responsiveness: all new elements (call button, modal window, updated footer) must display correctly and beautifully on smartphones and tablets. Code cleanliness: adjustments should not “break” existing scripts or styles of the site. Security: validation of the input data in the call form for spam protection. Please indicate your hourly rate, how much time the work will take, and the final cost in your response. Thank you!
