My site hosted on agava.ru. When this problem first time reveal, my site just open as a blank page. I cant come to Admin panel, cant make something, because i havent access to FTP on my plan.
i ask support and they say, that problem with Download Monitor plugin (he eat all memory). They simply deactivate all plugins. So i just delete this plugin and activate the rest.
All work now, but i still have this error after publication. And i cant make links noindex/nofollow with All in One SEO Pack. Cant make it with Robots Meta plugin.
I set option “nofollow”, save post, see error, open again post – and see standard “index/follow”.
But if i need correct post and save it, all changes saved (but always see this boring error).
Thx, WPYogi. I will try to change memory limit, maybe it help.
