Opencart - displays spaces before any content, issues with feeds

A virus has currently infiltrated the website. The site is not functioning properly. In particular, the main page is not working correctly. We need a developer who can fix this error as soon as possible.

A developer is needed with experience specifically in CS-Cart Multivendor for two related modifications on an existing online store. Task 1 - broken product photos. On the pages of some products, they do not display. Some photos show a "broken" image icon. Self-diagnosis revealed two different types of causes: The original photo exists on the server, but a specific non-standard (non-square) size needed for full-screen viewing of the photo is not generated (this function is from the third-party module "AB: Advanced Image Viewers," AlexBranding). Square sizes of the same photos are generated without problems. The original photo is completely absent on the server - a specific example and link will be provided upon response. Task 2 - warming up the cache of new products. The site automatically parses and adds new products every night (a separate cron script). Page caching is already set up and working, the warming of the main page and categories has already been done - but the pages of the new products themselves are still not warmed up immediately after import, so the first real buyer who opens a new product directly experiences slow "cold" loading. It is necessary to add automatic warming (curl/wget for the list of new products) immediately after the completion of the nightly import. All necessary access will be provided to you after selection. Work format: two separate stages with separate or joint payment for each task. First, diagnostics/analysis with written confirmation of the approach for each task, then implementation. Respond if you have relevant experience with CS-Cart Multivendor - details and a test task will be provided in personal correspondence.
