#1901 - Just upgraded from 1.5.6 to 2.0.6, not working anymore

Closed Installation created by jobst 7 years ago


Using a mix of Androids and Apple devices, never had any problems with SAS.

I had to purchase a new license (old running out) - hence I had to get the latest version of Opacus Acitivties Sync. License was correctly verified as it shows "valid".

I entered the required URL's for the sync as I have done many times before (noticing too you are now using 'sas.php' instead of just 'sas') , but it keeps telling me "login failed, please check username and password" but I am 100% sure those are correct!

Also the webpage "" has incorrect information as of the latest version.

    Hi Here's some debug info that happens when I execute the call Thunderbird/Android (Meetings and Tasks): https://DOMAIN_DELETED:443/PATH_DELETED/sas.php/calendars/USERNAME/default in a normal browser window.

    I have the same problem using Thunderbird/Lightning, this combo used to work. Just to check I deleted the calendar and followed the instructions on "" but using my URL, it did not work. I even updated the password to make sure that is correct, it did not work.

    Does this happen for all users of the Calendar, or just specific users?

    It could be a case sensitivity issue on the usernames, however your recreation of the Calendar from scratch probably rules that suggestion out.

    Do you have access to the Sugar Database? We might be able to do some diagnostics based on the values in the calendar* tables.

This case is public. Please leave out any sensitive information such as URLs, passwords, etc.
