My Joomla site breaks after I attempt to login in the front-end, returning an Error.

Error: 0 - Call to a member function get() on null


I can´t see anything in the console, I dont have any further information where the error come from. This happens after I restored my site with Akeeba backup, everything was fine until the restore. I tried to restore other older backups but the issue still the same. I have checked the log and tmp path and they are ok, the folders and files permissions are ok to, at last I have repaired the DB in the Cpanel but the problem persists. I dont know what to do more. The weird thing is that I still can make the login in the back-end without no problems. I´m confused. I dont have 50$ to buy a subscription in Akeeba, so i use the free version, thats why I need some help, because akeeba only give assistance to the pro version. I have joomla 3 running in php 7.0.9 version

Any help will be apreciated.

  • Have you tried contacting the Akeeba developer?

  • They only respond to those who have a paid subscription. And even these, they are slow to respond. still I do not have access to the Akeeba developer email.

    Yes! I did that, problem solved. I change the PHP 7 to 5.6 and everything is ok now.

    I agree with @SteffenNielsen that downgrading PHP to an older version is a fault finding step rather than a permanent solution and have updated my answer accordingly. Commented Aug 16, 2019 at 2:30

It's likely that you have an extension that is not compatible with PHP 7 yet.

I recommend:

  • temporarily switching back to PHP 5.6
  • upgrading all third party extensions to the latest versions

See https://docs.google.com/spreadsheets/d/1HJj02l3ByBvJF-Q67XXuGmrFvS8iIBEnDEcVcmwqzLc/edit?pref=2&pli=1#gid=0 for which extensions are compatible with PHP 7.0.

As far as I am aware, this document was created by Radek Suski.

Once everything is working again, switch back to a supported version of PHP.
