Multiple Issues 5.0.15

Hi Guys,

Sorry to bother you again & again after upgrade to 5.0.15 & to 5.0.16 but has almost broken my website. Finally, have restored it to previous date & I'm back to square one with my site left with EB 5.0.15

First, have a look at any link to blog post, they are broken e.g https://www.bankcircle.in/blog/129-tax-implications-on-your-groovy-second-home
Error:

Catchable fatal error: Argument 1 passed to EasyBlogCommentEasyDiscuss::html() must be an instance of EasyBlogTableBlog, instance of EasyBlogPost given, called in bankcircle.in/administrator/components/com_easyblog/includes/comment/comment.php on line 395 and defined in bankcircle.in/administrator/components/com_easyblog/includes/comment/adapters/easydiscuss.php on line 18

Second, have a look at https://www.bankcircle.in/sitemap , its broken
Error:

Warning: require_once(/bankcircle.in/components/com_easyblog/constants.php): failed to open stream: No such file or directory in /home/bankcirc/bankcircle.in/plugins/xmap/com_easyblog/com_easyblog.php on line 242



Fatal error: require_once(): Failed opening required '/bankcircle.in/components/com_easyblog/constants.php' (include_path='.:/usr/local/php55/pear') in /home/bankcirc/bankcircle.in/plugins/xmap/com_easyblog/com_easyblog.php on line 242

Third, must be related tp previous only, https://www.bankcircle.in/sitemap.xml returns blank

Finally, please upgrade to EB 5.0.16 at your end & check if these error doesnot occur.

It's been a week I've been struggling & one error removal leads to another, so pls help & do the needful.
