FAQ
My site says "TypeError: ... is not a function" after I updated my backend code. Can you fix that specific error?
Yes, this is one of the most common Velo issues, usually caused by mismatched imports between the old .jsw format and the newer .web.js module standard. I'll check your export syntax and webMethod permissions and get the function calling correctly again, usually within a day.
My site was working fine and suddenly broke without me touching any code is that even possible?
Yes, and it's more common than buyers expect. Wix pushes platform-level updates that occasionally break dynamic datasets, custom elements, or iframe bindings without warning. I'll inspect your browser console and network logs to isolate exactly which API call broke and patch it.
I only need one small filter fixed on my repeater do I have to order a full package?
No, small isolated fixes like a single filter or setFilter bug belong in the Basic tier. I scope packages by complexity, not by how the site looks overall, so you're never paying for work you don't need.
Can you actually connect my Wix site to external tools like Stripe, Zapier, or HubSpot?
Yes, using wix-http-functions I can expose custom REST endpoints on your Wix site so it can send and receive webhooks from external platforms. This effectively turns your Wix site into a lightweight backend that talks to your other business tools.
I embedded a script (like a tracking pixel or chart library) and it just won't render is that fixable in Wix?
Usually yes. Most rendering failures come from Wix's cross-origin iframe sandboxing or an outdated library version conflicting with custom elements. I'll rebuild the embed using a compatible Shadow DOM custom element so it renders reliably.
My site is getting slow as my database grows is that a hosting problem or a code problem?
In most cases it's a code problem, not hosting. Unindexed queries, missing pagination limits, or synchronous loops reading the database repeatedly cause exactly this. I'll refactor your Velo queries and add proper pagination so pages load fast again as your data scales.
I want to move my old Wix Editor site to Wix Studio can you migrate everything, including my database?
Yes. Wix doesn't offer an automatic migration path, so this requires manually rebuilding the site structure while carefully transferring your CMS collections, backend functions, and UI bindings into Studio. I scope this under the Premium tier given the manual rebuild work involved.
How do I know you'll actually understand my existing code instead of just rewriting it from scratch?
Before starting any fix, I review your existing site structure, database schema, and backend files first, and I'll flag anything that needs a larger rebuild versus a targeted patch before you're charged for it. You'll always know the real scope before work begins.
Do you only work in the classic Wix Editor, or can you build in Wix Studio too?
Both. I work across the classic Velo Code Panel and the newer Wix Studio IDE (the VS Code-based environment with Git integration), so the platform your site is built on doesn't limit what I can deliver.
What if the bug turns out to be bigger than what I described when I ordered?
If I find the issue is more involved than the original scope, I'll message you before doing any extra work, explain what changed, and let you decide whether to expand the order or keep it to the original fix. No surprise charges.
