Error after email account activation

This error happened to me recently from Dreamhost's mod_security, not sure why it didn't happen earlier. I'll paste the error here for Google searchers.

Hikashop 2.6.1 (old paid version)

Hello,

As Nicolas wrote :

I've just generated a new build of the 3.0.0 with a patch in order to avoid that problem.

The issue is fixed in HikaShop 3.x builds.
Please understand that HikaShop 2.6.1 has been released in January 2016 and that the support team can only provide bug support for latest version.
And we cannot unsure that HikaShop 2.6.x will continue to work properly with new Joomla version.
Best would be to update to latest version (and be careful since it would be a major update).
