I just installed wp-jalali, and I was able to reproduce the issue. I will run some tests and let you know.
Apparently, wp-jalali doesn’t return a number as expected for given date strings. It returns the Farsi representation of that number (like ۱۰ ). Slimstat expects to get a western number (0, 1, 2, etc) and thus the SQL generated to retrieve the results from the database is broken and returns an empty set. The only way to fix this problem is to tell the plugin’s developers to make their code compliant with PHP’s date format:
http://php.net/manual/en/function.date.php
Nevermind, I found a way to temporarily deactivate whatever wp-jalali does, so that it doesn’t interfere with our code 😉 Test 3.9.1 and see if it works for you.
Oh, thank you. You’re a good plugin developer!
A vote for Slimstat would be the good way to say thank you 🙂
excuse me, but it doesn’t work yet! there is no data in all pages!
you can see here
thank you!
Are you using version 3.9.1?
Yes. I was removed last version. then i install 3.9.1.
Really strange. I installed wp-jalali on my test site and after my changes to the code, it worked as expected. It must be something else then. Can you try deactivating your other plugins to see what happens?
