As others have mentioned, this is due to overzealous security measures on the server side. This is something only your ISP can tweak, and probably won’t. The problem is that certain words used to hack sites, most notably “curl” are being blocked, and hence the 403 error.
My solution, using suggestions from others in this forum, is to:
– Cut-and-paste your post to Notepad or somewhere else.
– Slowly cut-and-paste it back to WP, say, one paragraph at a time, and save the post.
– Repeat this until you get the 403 error.
– Once this happens, you know that problem word(s) is in the last paragraph.
Now repeat the above but type a few words, then save, repeat until you get 403. Eventually you’ll be able to identify the problem word(s).
Once you’ve indentified it, here are two possible solutions:
1. Split the word with a blank remark. Instead of ‘curl’ (a known problem word) type c<!-- -->url
2. Someone else suggested replacing the space before the problem word with the html ' '. Instead of ‘curl’ type curl
I’ve tried Option 1, and it worked for me.
Really helpful would be a list of all problem words, so we’d know what to look for, or a script that would automatically ‘fix’ all the problem words.
