Hello peiyouliao,
I have help you change to Error reporting to system default (because just now i turn on to Maximum and see what is that error), it look like work fine now.
In my opinion, you have to update to latest version of Easyblog, because some of the bug already fixed in latest version of Easyblog.
But take a note here when you update to latest version of Easyblog, you have to backup all your customization file including Easyblog module file.
Yes, if the plugin "Geommunity Map Locator Profile application" very helpful in your site, you have to consult to this plugin developer and see how it goes.
