Can not change CJBlog user avatar

Hi. I implemented CJBlog in my website to be able to post my articles in blog form. I am struggling with changing the avatar picture of my profile which is currently intended to be the only profile). I can see from examples that there is a "change avatar" link on the user profile layout. This link doesn't show on my user profile layout (see attached image). Also, I noticed that on articles which are accessed via CJBlog articles page, there is a Javascript error. If I view the website as guest, the error reads: TypeError: rating.raty(...).removeAttr(...).find(...).tooltip is not a function #7 http://localhost/asc12/media/com_cjblog/js/cjblog.min.js:166 #6 http://localhost/asc12/media/com_cjblog/js/cjblog.min.js:166:38 Object.CjBlogFactory.init_article() #5 http://localhost/asc12/media/com_cjblog/js/cjblog.min.js:284:40 HTMLDocument.() #4 http://localhost/asc12/media/jui/js/jquery.min.js:2:27295 j() #3 http://localhost/asc12/media/jui/js/jquery.min.js:2:28108 Object.k.fireWith () #2 http://localhost/asc12/media/jui/js/jquery.min.js:2:29942 Function.m.extend.ready() #1 http://localhost/asc12/media/jui/js/jquery.min.js:2:30308 HTMLDocument.J()   If I am logged in as super user, the error reads: TypeError: a.toLowerCase is not a function #11 http://localhost/asc12/media/system/js/mootools-core.js:95 #10 http://localhost/asc12/media/system/js/mootools-core.js:95:324 HTMLTextAreaElement.Element.implement.getProperty() #9 http://localhost/asc12/media/system/js/mootools-core.js:97:84 HTMLTextAreaElement.() #8 http://localhost/asc12/media/system/js/mootools-core.js:3:216 HTMLTextAreaElement.get() #7 http://localhost/asc12/media/com_cjlib/sceditor/minified/jquery.sceditor.bbcode.min.js:2:2587 new a.sceditor() #6 http://localhost/asc12/media/com_cjlib/sceditor/minified/jquery.sceditor.bbcode.min.js:3:18565 HTMLTextAreaElement.() #5 http://localhost/asc12/media/jui/js/jquery.min.js:2:2975 Function.m.extend.each() #4 http://localhost/asc12/media/jui/js/jquery.min.js:2:835 m.fn.m.each() #3 http://localhost/asc12/media/com_cjlib/sceditor/minified/jquery.sceditor.bbcode.min.js:3:18375 a.fn.sceditor() #2 http://localhost/asc12/blog1/user-profile:71:24 HTMLDocument.() #1 http://localhost/asc12/media/jui/js/jquery.min.js:2:27295 j()   The first of the attached images show my user profile (CJBlog user layout) and the second one shows an example of a blog article which was accessed via CJBlog articles page, while I was not logged into the website.   Cheers
