When I enter to the ‘Filter’ setting page, I found this error message:
Warning: str_repeat() [function.str-repeat]: Second argument has to be greater than or equal to 0 in /home/.../public_html/wp-content/plugins/post-plugin-library/admin_common_functions.php on line 598
Thereis 7 replications of that message on ‘Filter’ page.
They’re shown after text ‘Categories to exclude/include:’ and before list of categories.
What is happened, and how to solve that ?
