XenForo Add-on Bug Fixes

I have an existing XenForo add-on that refuses to install cleanly on some forums. The installation routine stalls, throws database errors, and occasionally leaves half-written tables behind. I need an experienced XenForo developer to trace and eliminate these bugs so the add-on installs and runs without manual intervention on current XenForo releases.

What I already know: the problems surface during the install step rather than in day-to-day use, so the work will be focused on the add-on’s installer classes, schema creation and any callbacks that fire during setup. If, while testing, you spot other edge-case issues—especially anything that could later break user interface elements or data handling—I’d like them fixed within the same pass so we end up with a truly stable build.

Deliverables
• Clean, commented code for the installer/upgrade routines
• A brief change log summarising each fix
• Confirmation (screenshots or short loom) that a fresh install and an upgrade install both complete successfully on a vanilla XenForo instance

You’ll be free to work in whatever environment you prefer; I can supply a test database and blank XF install if needed. Please include a short note on similar XenForo bug-fixing work you’ve handled so I can gauge fit and turnaround time.
