Api error with purge cache


I started to get a huge amount of errors without changing any settings. I managed to find out only one solution which was from 3 years old topic and was not the fix for this problem, close by, though. What should I do to fix this?


[Cloudflare] ERROR: [CLIENT API] Array

[type] => request
[path] => https://api.cloudflare.com/client/v4/zones/82c3a07e9457a05f9948235af84e6082/purge_cache
[timeout] => 30
[method] => DELETE
[headers] => Array
[Content-Type] => application/json
[X-Auth-Email] => xxxx
[X-Auth-Key] => xxxx

[body] => {"files":["https:   and here comes huuuuge list of pages.

Also typical error:

[Cloudflare] ERROR: [CLIENT API] Array
[type] => response
[reason] => Bad Request
[code] => 400

I have the exact same problem since updating to Cloudflare Plugin 3.5.0. Does anyone have an Idea?
