Hi Hamidul

Have you cleared your caches? It might be still reading data from the cache.

Hi Jorge,

Thanks for replying. I have enabled the DEBUG level for the necessary categories. However, it's not giving the right information. Even I deleted all rows from the portalpreferences table. But still, I have the same problem. After enabling the DEBUG I see below stack trace

RE: Unexpected character 'c' (code 99) in prolog; expected '<'

Hi Hamidul,

According to your exception, you have a PortletPreferences entry in database with wrong data: its internal XML cannot be parsed.

There is a PortletPreferences entry for each portlet in each page (and other additional PortletPreferences that are not linked to an specific page)

Try activating DEBUG traces of com.liferay.exportimport category and repeat the operation. You will have additional DEBUG traces with the information about which page and portlet with the wrong data is throwing the expcetion and you will be able to delete or fix it before exporting the LAR file.

Regards,
Jorge Díaz
