Export/Import tool Error When Refreshing Modification Page

Hi,

I have installed the opencart-2-0-x-export-import-multilingual-2-xx.ocmod.zip, and after installation, there is the "Export/Import Tool for OpenCart 2.0.x" under the Modification list.

But when I click refresh, this error comes:

Fatal error: Call to a member function getElementsByTagName() on a non-object in /home/myit/public_html/admin/controller/extension/modification.php on line 153

How can I fix this?

Thanks

Hi,
Same problem with the same extension here...

Any solutions?
