Object reference not set to an Instance of an object error

Hi,

When we try to change the category for a blog post in sitefinity 5.4 we are getting the error: "Object Reference not set to Instance of an Object" Is there a fix for this issue?

Thanks,
Annie Enchakattu

This is an urgent issue for us, since we create a lot of news articles and post them as drafts and later have to change the name of the draft. Currently this issue is causing a lot of pain and lost time for our business users. Anything you can do to help address it would be appreciated!

Hi,

Thank you for contacting us.

This is a general error and does not provide information regarding the cause of the problem. In the interest of resolving the issue quicker, please do the following: Go to App_Data/Sitefinity/Logs, delete the files there. Reproduce the issue, and archive the newly generated log file. 

After that open a support ticket and attach the file and also include information if the issue reproduces with a local copy of the project. Also, does it happen only for blog posts or other content items as well?

Thank you in advance.
