Just tried to install the new upgrade. I am an 7.7.1 on php 7 having lots of issues with warnings and dashlets. Tried to install 7.7.2 upgrade and now getting error. The uploaded file is not compatible with this version of SuiteCRM 7.7.1.
I have the same problem. I’ve tried to upgrade from 7.7.1 to 7.7.2 and nohting seems to happen.
I have the exactly same issue.
I believe the package has been recently updated, so this should be resolved.
Would it be possible to re-download the package: https://suitecrm.com/download
and try upgrading again?
Please let us know if you come across any issues!
It did fix the problem and the calendar is back up! Cheers!
