According to your information above, you are running JIRA 5.1.x having installed Atlassian Universal Plugin Manager (UPM) v2.1.5: as you can read out of the file name of my Gantt-Chart you have to upgrade UPM to version 2.7.7 ("gantt-2.1.6-JIRA5.1-UPM2.7.7.jar").

The current UPM version is 2.7.8: if you upgrade to that version, please download the related JAR of my Gantt-Chart from my server at http://www.polscheit.de/plugins/jira/gantt-chart/gantt-2.1.7-JIRA5.1-UPM2.7.8.jar

Regards,
Frank

I have installed version 2.7.8, but the error stays the same.

Any ideas?

Did you upgrade BOTH?

1. Atlassian UPM to v2.7.8 AND THEN
2. http://www.polscheit.de/plugins/jira/gantt-chart/gantt-2.1.7-JIRA5.1-UPM2.7.8.jar?

Regards,
Frank

Ah sorry, wrong thread. I have a similar problem with my structure-plugin.

Sorry!

Frank,

Is there a version of your Gantt plugin that works with UPM 2.16.5?

Thanks.

Yes, please download my latest pre-v3.1.5 from my server at http://www.polscheit.de/plugins/jira/gantt-chart/gantt-3.1.5-JIRA6.jar and install the JAR-file using JIRA’s „upload“ button on page „manage add-ons“ as system-administrator.

I have tested this for you a minute ago using JIRA 6.2.5 together with UPM 2.16.5.

Kind regards,
Frank
