Hi,
I want to report that after update the joomla to 3.6.2 I notice that the number of the pages have disappeared like the image that I have attached. Also have disappeared the index of the indexes of the of the filter and the descriptions of the paths, I have also attached image to show the problems.

What can I do?

Hi,

These problems look like they originate from your Joomla template and thus are not linked to the version of Joomla you're using.
If you switch to the default template of Joomla, does it work properly ?
And if you use your template after renaming the folder templates/YOUR_TEMPLATE/html/ via FTP, does it work properly ?
