Hello Vincent,
I am sorry about the issue.
Are you referring to reviews for products, for blog articles or in the Comments and Ratings object?
Thank you for clarifying.
I remain available.

Bonjour Vincent,
Je suis désolé pour le problème rencontré.
Faites-vous référence aux avis sur les produits, aux articles du blog ou à l’objet Commentaires et évaluations ?
Merci de bien vouloir apporter cette précision.
Je reste à votre disposition.

Bonjour, j'utilise l'objet commentaires et notes.

Vincent

I use Comments and Ratings object.

Vincenet

Hello Vincent,
what settings are you using, send to file or send to database for the storage of comments?

Online translation:

Bonjour Vincent,
Quels paramètres utilisez-vous pour le stockage des commentaires : l'enregistrement dans un fichier ou dans une base de données ?

I use send to database. in the website’s online dashboard; all the tests are passing, including the database test. However, all the comments have disappeared here too.

Vincent

Hello Vincent,
if you add a new comment/review now, does it work, or do you get an error/it is not displayed?
If it is added, please check the contents of your database, has a new separate table been generated to store this?
I remain available.

Hello Eric, when I add a new commet, it's work. In php my admin, In phpMyAdmin, I noticed that a new table had been created. The old is still there, whith an other table name of course.

Vincent

Hello Vincent,
do the two tables have a different ID in their name?

Hello, I'm not sure whar is the ID. their complete names are : 

w5_06vqoyzp_10_01_comments

w5_ed0f48c3_10_01_comments

Vincent

06vqoyzp and ed0f48c3 are project IDs.
Each project should have a unique ID, which is also seen in the table names.
If there are multiple IDs, it means that it has changed for this project.
Have you, for example, recently used the duplicate function to create a copy of the project?
I remain available.

Hello Eric,

yes it's possible that I duplicated project. If I’ve understood the situation correctly, do I need to put the version corresponding to this ID back online? Is that the only solution?

Vincent

Hello Vincent,
yes, you would need to restore the original ID, so that the project can connect to the previous tables again.
If you can provide me with a copy of the project, I can go ahead and do this, then send the project back.
You can export it in Step 5 - Export, choosing the “Export the project” option to generate an IWZIP file, making sure not to use the options to include backup and preview files so that the size of the file is reduced.
You can then upload the file with SwissTransfer, TransferNow or similar services, and provide a download link to support @ incomedia.eu (without the spaces).
Thank you.

Hello Vincent,
I downloaded the project.
As a confirmation, when checking your database the comments can be found in the w5_ed0f48c3_10_01_comments table, correct?

Hello Eric, That's it

Vincent

Hello,
I sent via mail the download link for the project with the updated ID, you should be able to connect to the original tables with comments after exporting it.
I remain available.
