I have 2 websites running on WordPress, for some reason since around a week ago every time i try to do changes on the website i can only make 5 or 6 changes (like adding new products or pictures) before an error shows up (one of the websites being an online store on which im trying to move products to new categories and since this issue came up is taking me forever and becoming frustrating).
The error pretty much logs me out and shows a blank page with the following message:
No data received
Unable to load the web page because the server sent no data.
Error code: ERR_EMPTY_RESPONSE
This stays there for a few minutes even if the page is re-loaded until it just simply fixes itself, but keeps happening every time a few changes to the website are made.
I called my hosting company and they insist that this might be a security measurement from WordPress since this started happening on all my websites.
Anyone has any idea why this is happening now and what can i do to prevent it from keep happening?
I would really appreciate some help.
