For months we did not do any changes to the templates, and everything has always gone well.

"Rejected by server" are usually related to "mod_security" configuration in the server. Probably your host has recently installed mod_security.

This is NOT related to webtemplates or any application in this regard actually, it is a server related issue. Whenever you try to send such an information to server, mod_security can stop you when it thinks its content is suspicious.

One alternative is to disable it, the other is to disable it only for admincp folder and use admin cp webtemplate edit to edit HTML webtemplates and last alternative is to play with its (mod_security) configuration to whitelist your content.
