Bug ERROR RUNNING SYSTEM CHECK

[WEF]

Hi, I have a strange mistake when I run system check.

I attach a screenshot of the error so that you can understand me better.

When I run system check, the process never ends and javascript error jumps out:

Uncaught TypeError: Cannot read property 'getElementsByTagName' of null
at Object.ran_test (vboptimise.js?v=1:7)
at Object.handleTransactionResponse (connection-min.js:13)
at connection-min.js:13

Do you have any idea how I can fix this? Thank you.

Regards

Can you please check your server error log to see if there's any more information?

You were right, there were some errors in the code of some files.

I've been able to work it out.

Thank you.
