Message: Call to a member function get() on null

Since two weeks I get every day a message from my akeeba-system “A PHP Exception occurred on your site…….. “
Attached you will find the whole report.
The mistake I am not able to reproduce, but it occurs between 8 and 50 times a day.
I do not really know if someone tries to hack my site or is it a hika-bug.

Could you help me?
Best regards
Frank

Hi,

Well, the URL of the page which generated that error is not valid, so it's normal you get an error.
What is the URL of the page where you got that URL which generated that error ?

The site is: messerguide.de
I thought the information is in the attached stacktrace.

Hi,

No the referrer is not part of the information in the stacktrace.
So I still don't know where you got that URL from.

Ahh, ok now I understand.

The stacktrace is send from Akeeba Admintools. The Component on my Joomlainstallation. It is send by info@messerguide.de.
The full information you will see at the new attached stacktrace.

Hi,

Well, there is not much you can do here.
What this all means is that you have a bot ( www.semrush.com/bot/ ) which, for some reason, found the URL /index.php?Itemid=101&option=com_hikashop&task=show and tried to crawl it. But since that URL link is not valid, it came back with an error. And AdminTools catched the error and sent you an email about it.
I would just ignore it if I were you.

ok, thank you.
