Okay, I got the VPN working, however it is so slow that I can’t possibly do anything when connected. It takes over 10 minutes to load a single page.
I managed to load the plugins page, and I noticed that the plugin is outdated. Please update to version 4.26.4 to make sure none of the bugs are caused by something that had been fixed before.
1. Make sure the reset button action is set to trigger the search, it’s a common mistake: https://i.imgur.com/xPqVoNW.png
2. I can’t test this unfortunately, none of the pages fully load on my end.
3. It is not possible to search custom database tables – the data has to be in the supported wordpress tables, like custom fields, taxonomy terms and posts table.
4. I can’t really see any issues by looking at the filters, but let me know if there is something specific
I will have to uninstall the custom VPN software for security reasons – I should not have had it in the first place. If you can, please make a live/test/staging website that is accessible publicly. That will make this 100x faster and easier for me to debug if there is something wrong.
