Front end saves quotation marks (“) as escape chars

I tried this but I was unable to reproduce the problem. ?Try switching to a default theme (e.g., Twenty Twenty-Three) and see if that resolves the problem. If not, try disabling all of the plugins other than Events Manager and then enable them one at a time to see which one is causing the problem.

Thank you for your quick response.
I now installed the plugin on a different (“empty”) site, for testing. I found out that the problem only occurs if the plugin generates an error message before saving the event to the database.
Eg.: A new user does not check the agreement box at the bottom.
Or: You forget to provide an event date.
Consequently, an error message is generated, and the field contents that have already been provided by the user are then re-displayed. If the text contains characters that would have to be escaped, you will see the additional escape character.
Hope that helps.

I tried to add an event without providing a date and it gave me an error message and didn’t create the event. How did you create the agreement box for new users? Are you using a GPDR plugin?

If there is an error it doesn’t create the event, that’s right. However, the title field below the error message now contains the misformatted text. If I correct the errors, and leave the other things that have already been provided as they are, all data are now stored in the database, including the misformatted title.
And no, I do not use a GDPR plugin. This is a setting of your own plugin: Privacy > Consent > Remembering consent

First of all I am not the owner of the plugin. I’m just trying to help people out in the community forum.

I was having trouble reproducing the problem because I was using the following for the title:

 “Bunte Gemeinde”

Once I changed it to this, I was able to reproduce the problem:

 "Bunte Gemeinde"

Hopefully, the plugin owner will fix this.

Oh I see! Thanks anyway.

You can fix this problem by adding the following code snippet:

add_filter( 'em_event_get_post', function( $result, $EM_Event ) {
    if ( ! empty($EM_Event->event_name ) )
        $EM_Event->event_name = stripslashes( $EM_Event->event_name );
    return $result;
}, 10, 2 );

You can use the Code Snippets plugin to add the code snippet.

It works. Thanks so much.
