We use a site monitor "UR", and I whitelisted their IP addresses in our WHM. On one of the sites we host, about half of times the UR bot checks in, it results in a 403 error. I double-checked my whitelist/blacklist, then decided in must be the htaccess. Below are typical recent error msg followed by sanitized htaccess. Bold IP is legit for the UR bot.

Code:
[Tue Dec 04 11:55:30.801144 2018] [access_compat:error] [pid 9603:tid 47443861387008] [client [B]63.143.xx.xxx[/B]:34758] AH01797: client denied by server configuration: /home/admin/public_html/exampledomain.com/wp-content/cache/all/index.html, referer: [URL]https://exampledomain.com/[/URL]

Hi @LukeFive Dev

That first IFModule looks like it's specifically adding a rewritecond to the directory you're experiencing an issue with. Does the issue persist with that IFModule commented out?
