SyntaxError when trying to add new subscription.

Wallos v2.4.2
Docker 26.1.3

When I try to add a new subscription, I receive the following error:

SyntaxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON data

I don't know what this means nor how to resolve it. I did a Google search for information, but I didn't understand anything I read.

Could anyone point me in the right direction?

If you could open the developer tools on the browser, open the network tab and try to add the subscription again.
Click on the failed add.php and go the response tab. It should give more information on what the error actually is.
Then please paste the error message here.

Thanks.

I did as you said, but for some reason it just worked when I added the subscription, so it must have just been a small glitch. Thanks for the advice, though.
