Hi.
I have a strange error on my website – still in development.
Using constructor I created Elementor Single Post design. When I apply a rule to use this design for a certain category of posts, it is showing the post with correct design, but if I need to edit a certain post from that category using Elementor, I get the error below and I’m not able to edit it. If I delete the rule from Single post design, and I try again, I’m able to edit it.
Please help me to solve this issue.
Thank you!

Hi,

Thank you for reaching out to us.

After reviewing the reported errors, we did not find any indication that they are related to our theme or core plugin. It is most likely that the issue originates from the plugin elements. To begin troubleshooting, we recommend reviewing and following the solutions provided in the following article: https://elementor.com/help/500-error/

If the suggested solutions do not resolve the issue, please provide us with access to your WordPress admin panel and FTP. This will allow us to confirm that the problem is not caused by our theme. In parallel, we also recommend reaching out to the plugin’s support team for further assistance.

To grant WP-Admin access, please proceed to create a new user account with an administrator role through your WordPress Dashboard. Once the account is established, you may securely transmit the username and password to us via the Private Content section designated for this purpose.

For FTP access, we require the following details: FTP host, FTP username, FTP password, FTP port, and FTP encryption type. If you need assistance in creating these credentials, please reach out to your hosting provider who will guide you through the process.

Warm Regards,
The 8Theme Team
