Php issue while render the module?

Hello Stackideas team,

I just bought a comment extension called "JLex Comment",
and while I'm trying to integrate this comment with EasyBlog (which JLex support integration with Easyblog)
it always have some problems while I try to turn on the settings in "JLex Comment".
(like apply the avatar source from EasyBlog, set up guests' restrction..)

I first go to JLex's company to ask about this question,
but I just get feedback that " You should contact with Stackidea Team....
The error is system can't find file components/com_easyblog/includes/gettable/gettable.php when render module."

It seems we're having issue with the easyblog php file.
Please let me know if you could help us with this issue.

I've attached the error file,
and you could check the error in the picture.
