Have several sites, all can be saved, except for the one heavy on Wix Code. Have done all the obvious (incognito mode, clear cache, different browsers).
I put it here, because I had the same problem about a year ago, when, after a couple of weeks of not being able to work, it turned out that a Wix Code function name "sleep", was flagged (erroneously) as SQL-injection somewhere down the line.
Console window shows exactly the same error : Failed to load resource: net::ERR_CONNECTION_RESET.
I have made no code changes to the site for a long time.
I suspect something similar is going on. I really would appreciate any help, I am stuck.
EDIT: could somebody from Wix please help me? Regular support cannot help me and I am in deep trouble, I desperately need to change some things.
