Getting 520 Server Unavailable Error

Hi. When trying to edit pages on my WordPress site running on Cloudflare, I have an issue where the site throws a "520 Server Unavailable" error from Cloudflare. I looked at my server logs and saw this error that shows twice the moment the 520 error appears:

2022-08-16 18:41:38.825160 [NOTICE] [49352] [T0] [127.0.0.1:43402#APVH_ancienttreearchive.org:443] [STDERR] PHP Notice: Trying to get property 'post_type' of non-object in /home/ancient/public_html/wp-content/plugins/click-pledge-connect/clickandpledge_form.php on line 293

Is this something you can look into? This has been happening for some time (over a year) when trying to edit the site (I'm using Divi). Only now did I learn that I needed to disable Cloudflare to be able to see the server error log properly.

I had opened a ticket and included login info. They asked me to post my issue here.

I'm not 100% sure that the plugin is the source of my troubles or if that error is serious, but I thought you should know anyway.

Thanks
