Not able to access jira project

[Srinivasan Gunasekaran]

When we open the project in JIRA, the main page gets greyed out and it is not able to click. Looks like disabled.

Please help.

What do you mean by "main page". Do you have Jira on your own server or on the cloud? 

Could you provide a screenshot?

[Srinivasan Gunasekaran]

Not in cloud... When i open a project , the left side links are allowed to click and right pane are greyed out... as below...

Do you see some errors in the log files?

[Srinivasan Gunasekaran]

Please find the error log screen shot

Hmm. from what I can see, the error comes from a plugin from iDalko. Do you have installed Table Grid Editor? 

Does it work, if you disable this plugin?

[Srinivasan Gunasekaran]

We have a Table Grid Editor and used in the project.

[Thomas Schlegel]

and, did you try to disable it?

[Srinivasan Gunasekaran]

As many users are using JIRA, and lot of projects have used table grid, we didn't disabled the plugin.
