My next step is to access a copy of your website, to check for conflicts and test solutions in it, so I don't harm your live website. Nonetheless, I got multiple errors, and couldn't manage to create the needed copy.
In this case, please create a staging version of the website. You can use a plugin to achieve that, or reach out to your hosting support, ad they might be able to help you to create a staging website. Please send me the link to it here, when you are done. Thank you for the cooperation on this matter.
Thank you for sharing. I've analyzed it, and I'm getting a second opinion with my colleagues. I'll get back to you once I have new information. Thank you for your patience.
Your ticket's been escalated, and I will get back to you as soon as I hear from our devs, which can take a few days. I'll keep you updated. Thank you for your patience.
