Counts disappeared

Disable all your plugins.
Enable only Page View.
Now go enabling one by one to see which is the one that prevents the action.

I am having the same problem. Every time you go into wordpress or update a page the count vanishes. This has happened ever since I updated the plugin to version 1.3.0 Before that everything was fine and I have not changed or added any new plugins since then. You can manually add a count but that would require you to keep a daily tally of your previous page counts just in case it wipes out your totals again. Tedious to say the least and renders the plugin useless.

Same here, this has nothing to do with other plugins, I installed on a clean new install of wordpress with this being the only plugin and it still does it. Everything after the comma gets removed. you can remove the comma, update and it adds a comma. update again with a comma already there and it removed the digits to the right of the comma and also the comma vanishes. Any number up to 999 will be ok but put a comma in e.g 9,99 or 99,9 or ,999 and it goes wrong the ,999 just defaults to 0

disabled all plugins on another website with bulk actions, enabled page view only and still same issue

Same as you milly updated to 1.3.0 and it all got messed up, must be a fault in the coding somewhere, this is not a plugin compatibility issue, I would suggest you compare your coding from 1.2.1 as that version worked ok for me
