And also in the log of the server:
Illegal string offset ‘record_id’ in /home/deb/domains/nameofwebsite/public_html/wp-content/plugins/participants-database/participants-database.php on line 721\n
and
Cannot assign an empty string to a string offset in /home/deb/domains/nameofwebsite/public_html/wp-content/plugins/participants-database/participants-database.php on line 721\n, referer: https://b12-institute.nl/wp-admin/admin.php?page=participants-database
I checked the page of the shortcode still was there and also created a new page with the shortcode but that did not solve the problem
The link from the mail works:
https://namewebsite/bewerk-inschrijving/?pid=5Z88V
The link form the backend does not:
https://namewebsite/bewerk-inschrijving/?pdb=874
Is it strange that the mail link uses pid and the backend pdb?
Those two links are for two different things. The link in the mail is the “private link” to edit the record on the frontend.
The link you seeing in the backend is the “single record” link, which simply shows the record data. This uses the [pdb_single] shortcode, and that is configured in the plugin settings under the “list display” tab. To use this feature, you need to set up a single record page that has the [pdb_single] shortcode.
