Hey! Had the same issue last week. Turns out my server was blocking POST requests for some reason.
Check if your hosting provider has mod_security enabled—it sometimes flags legit requests as suspicious.
Also, try temporarily disabling plugins one by one. A rogue plugin could be messing with your form submissions.
For quick debugging, use Chrome DevTools (F12) to inspect the network tab when the 405 not allowed error hits.
