I bought JLexReview  and I installed it on Joomla! 3.3.6 Stable but I have many errors.

For example on dashboard (Components):

Strict Standards: Declaration of JLexReviewViewDashboard::display() should be compatible with JLView::display($tpl = NULL, $toolbar = true) in /home/xxxxxx/public_html/administrator/components/com_jlexreview/views/dashboard/view.html.php on line 21

If I use the plugin "Content - JLexReview" on an article Joomla into a specific category, when I load  this one :


"Strict Standards: Only variables should be assigned by reference in /home/xxxx/public_html/plugins/content/jlexreview/jlexreview.php on line 23

Strict Standards: Only variables should be assigned by reference in /home/xxxx/public_html/plugins/content/jlexreview/jlexreview.php on line 23

Strict Standards: Only variables should be assigned by reference in /home/xxxxxx/public_html/components/com_jlexreview/load.php on line 24

Strict Standards: Non-static method JLexReviewHelperSite::keyEncode() should not be called statically, assuming $this from incompatible context in /home/xxxxxx/public_html/components/com_jlexreview/document.php on line 228

Help me!Thanks
