Half the admin page

hey, i have the same issue with 8.0 php version.
try to downgrade the php version to 7.4 or 7.3 .

Thanks @waaedazzam ?? too bad it’s impossible to downgrade for us because we’re on a containerised WP…

string on string in simple-csv-xls-exporter/classes/simple-csv-exporter-settings.php:357″

WordPress version 6.1.1
Thème actif?: Twenty Twenty-Three (version 1.0)

@ravanh could you please tell me what you were trying to do exactly when the error appeared?

the plugin has been successfully tested (activation and default export) with PHP 8.0

Hi @shambix I had just installed and activated the plugin. The error occurred after modifying (and saving) the plugin settings for the first time… After that, I could no longer modify settings as the admin page was broken.

Maybe relevant: I chose a custom post type for the export settings. I was hoping to include custom taxonomies but those were not (yet) available. I then saved the options in the hope that after selecting the custom post type, its associated custom taxonomies would be available for selection. Sadly, the error prevented further testing of the plugin.

@ravanh I will try to test this case and release an update as soon as I can identify the issue.

Can you confirm that the post type is searchable? is it a custom one? a system one? what other data did you select for export?

Yes, a public (and searchable) custom post type. I don’t remember what other data I selected. At least the Title, Content and Excerpt but the custom taxonomies where not available at that time…
