Fix Facebook Marketplace Access

Facebook Marketplace has locked me out completely. Each time I try to open it I’m met with an error screen, so I can’t even start listing new items. I suspect the situation is complicated by the fact that I’ve operated more than one Facebook account in the past, and I’m worried that overlap is now triggering Marketplace’s security filters.

Here’s what I need from you: diagnose the exact cause of the block, outline the steps required to regain full Marketplace access, and implement (or guide me through) the fix so I can place ads again without risking another lockout. If the problem involves account merges, identity verification, appealing to Meta support, cache or device conflicts—whatever it is—I want a clean, repeatable solution and clear documentation of everything done.

Please send a detailed project proposal describing:
• How you will pinpoint the specific trigger behind the error message
• The tools or channels (support tickets, policy reviews, account audits, etc.) you will use
• Your estimated timeline for restoring normal Marketplace functionality

I’ll move forward quickly with the freelancer whose plan shows the clearest path to a permanent resolution.
