Hi again everybody!
Thanks for your patience regarding this issue today!
Earlier today, I released a plugin update (TablePress 1.9.2) that prevents further corruption of TablePress tables after editing them on WordPress 5.1. Please update to TablePress 1.9.2.
I can now also offer a solution to easily restore TablePress tables that where corrupted due to this bug:
- To restore your corrupted tables, I developed a small custom WordPress plugin, a TablePress Extension. Please download that as a ZIP archive from https://tablepress.org/downloads/extensions/tablepress-fix-corrupted-tables.zip
- In your WordPress admin dashboard, go to the “Plugins” -> “Add New”, and click the “Upload Plugin” button near the top.
- Then, choose the ZIP file that you downloaded in step 1 and upload it. (Alternatively, you could extract the ZIP archive and upload the contained folder to your site’s /wp-content/plugins/ folder via your FTP program.)
- On the next screen, click the “Activate Plugin” button.
- The TablePress Extension will then try simple search/replace operations in your database to fix the internal data format of the TablePress tables.
- You should then see a notice text at the top of the screen about the process, and a suggestion to create a backup.
- Finally, you may go to the “Plugins” screen and “Deactivate” and then “Delete” the “TablePress Extension: Fix corrupted tables” plugin again.
Again, I’m really sorry that this issue happened due to a bug in WordPress, and was not caught earlier during the testing phase. With TablePress 1.9.2, you should no longer experience corrupted tables from this issue.
Best wishes,
Tobias
