Hi,
Iāve recently ran through an upgrade myself from 7.1.x to 7.3.2 using the package on the download page, and it ran without any issue.
I assume you attempted the upgrade with a recent version of the package? (i.e, downloaded it from the site recently)
When upgrading from 7.1.x to 7.3.2, I believe you might be met with a white-ish screen, but the CRM should still be functional. I bleieve this is because thereās now a new theme, (SuiteR), and you will need to set your theme.
You can do this by going into your user profile settings, (Can be done by clicking your name on the top-right of the CRM), go into the āThemesā tab, select a theme, and Save.
That should hopefully resolve your issue!
Regarding the Errors youāve posted, it seems like they are largely warnings/notices, which can be hidden as they will have no affect on a deployed SuiteCRM.
You can hide/disable these in a few ways.
You can disable error reporting in your php.ini file.
Or if you enter the line:
ini_set(ādisplay_errorsā,0);
into your SuiteCRMās index.php file, this should have a similar effect.
(This line can be removed at any time, should you wish to show errors again)
If you perform the above, are you still having issue?
