WordPress migration support and diagnostics · SaaS
A SaaS marketing site froze on mobile menu tap right after a host migration. The team was about to roll the whole migration back. We traced it to two plugins loading conflicting jQuery versions, deduped the load order, and shipped a permanent fix in one session. Full recorded evidence is available on request during a discovery call.
Mobile users could not open the navigation. A console error showed jQuery was being loaded twice with conflicting versions, breaking the menu toggle script. The old host had silently merged the duplicate. The new host did not.
Reproduced the freeze on a real device, captured the console and network trace.
Identified the two plugins enqueueing their own jQuery copies.
Wrote a small mu-plugin to dedupe jQuery and force the WordPress core version.
Retested every interactive element across 8 device and browser combinations.
Mobile navigation was working again the same session. No rollback needed. The mu-plugin became part of the client's standard migration checklist so the same trap never happens again on future host changes.
We were one hour from rolling back the entire migration. They fixed it in one call and explained exactly why. Client identity withheld under NDA. Full Loom recording and dated evidence are available on request during a 15 minute discovery call.
Some hosts ship aggressive script optimisation that silently dedupes duplicate libraries. Move off that host and the underlying bug surfaces.
Yes. Plugin script conflicts and cache layer differences are the two most common post migration breakages we see.
We have 500 plus recorded engineer sessions covering migrations, malware cleanups, speed wins, and emergency recoveries. Most clients are under NDA, so we cannot publish them publicly. On a 20 minute discovery call we will show you the recordings, dashboards, and before and after numbers most relevant to your situation.
