Critical error with specific Portfolio Post

Hello,

Thank you for reaching out to us.

We understand that you are experiencing a critical error on your website after editing a Portfolio post using Elementor, and we appreciate the detailed information you have provided.

Based on your description, it appears that the issue may be related to the specific content or widget used within the problematic post (https://www.dorishartwich.de/project/kataloge-fs25/), especially since other portfolio posts are functioning correctly. Since you mentioned that the Flipbook plugin is part of the content and deactivating it did not resolve the issue, it is possible that there is a conflict or a corrupted element within that particular post.

To assist you further, we kindly ask you to perform the following steps:

1. Enable WordPress Debug Mode:
Please enable WP_DEBUG in your wp-config.php file to get more detailed error messages. This will help identify the exact cause of the issue.

2. Check for Console or Server Errors:
If possible, please check your browser console and server error logs for any related messages when trying to access the problematic post.

3. Try Rebuilding the Post:
As a temporary workaround, you may try duplicating a working portfolio post and then re-adding the content step by step. This can help isolate the element causing the issue.

4. Provide Temporary FTP Access.
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.

Please let us know once you have enabled debug mode or if you are able to share any error messages that appear.

Best Regards,
8Theme’s Team
