Need a specialist with knowledge of PHP, HTML, CSS, and WordPressTechnical Task Project: refinement of the WordPress site Main site: https://podohealth.pl/ Backup site with implementation examples: https://podolog-wroclaw.com.pl/ All changes need to be implemented directly in the site code or through the appropriate mechanisms of WordPress, WooCommerce, and installed plugins. It is important that the changes made do not disappear after updating the theme or plugins. If necessary, a child theme should be used. All points of the technical task have already been implemented on the backup site. Changes were made there before transferring to the main site. Unfortunately, before starting work on the backup hosting, the current version of the main site was not deployed. Because of this, transferring the completed changes to the main version turned out to be impossible due to bugs with site speed, etc. Therefore, it is now necessary to copy all files responsible for the changes, raise the current version of the site, implement these changes, and fix bugs (the site speed has dropped) and then raise the current version of the site on the main hosting, or re-implement them directly on the current version of the site in such a way that it does not interfere with users and does not crash the site.
