Hi!

Joomla version: 3.9.13
PHP version: 7.2
JEvents version: 3.4.50
Managed Locations version: 3.5.4

On creating or editing an event in the frontend and hitting "Select location", instead of a modal popup with the locations to choose from, the client gets a 404 in the modal popup with error message "0 Cannot assign by reference to overloaded object".

I had this issue in the backend as well and managed to solve it by changing plugins\jevents\jevlocations\jevlocations.php line 598:

$html[] = '<input type="hidden" name="location" id="locn" value="' . $row->location() . '"/>';

to

$html = [];
$html[] = '<input type="hidden" name="location" id="locn" value="' . $row->location() . '"/>';

That works - for the backend.
But in the frontend, the error is still there and my client can not select a location.

What should I do to fix this?

Thanks,
Anja
Hello,

I just downloaded and reinstalled managed locations and all is fine.

Please try your self and let me know if you have issues.

I am going to say someone has restored files but not the database at some point, since our support reads the manifest files and not the database.

Many thanks
Tony

Hello Anja,

You need to update your JEvents Managed Locations to V3.5.x

Many thanks

Can you please login with your club account and provide super user details so I can debug it.

Also, provide the JEvents Support info from the JEvents backend.

Many thanks

About the super user details / club account: my client has a club account, I don't mind logging in with their account, but I don't want to involve them in the conversation.

So: client information in private section. Super user information for develop site also in private section.

Yes, a lot happened on this site before we were asked for help in maintaining it and fixing issues.

I've installed managed locations once again on the live site as well and everything works fine now.

Thank you Tony!
