Hi,

Trying to install the latest version downloaded but it keeps giving 500 error after entering database info.

Error is:

`mautic.ERROR: SCHEMA ERROR: There is no column with name 'attribution' on table 'ma_leads'.`

Any ideas?

Thanks

Joseph

Hi bizcrony,

I’m installing it on CentOS running Virtualmin. I was able to successfully install Mautic in the same system a couple years ago to test it out.

Any ideas?

Thanks for your help.

I’ve deleted the database and re-uploaded files to try to install but keep getting the same error. Has anyone encountered this issue? Any suggestions? I’d really like to try Mautic again if possible. Thanks
