Hello guys, i have installed OJS 3.1.1.0 and I’m trying to enable the Usage Statistics plugin, but when i try to save the configuration on the apache2 log show me an error:

Hi @Marlon_Ramirez,

Those warnings are cosmetic, but can be resolved by changing bool to 'bool' on the lines referenced. This has already been fixed for the next release of OJS.

Hi @Marlon_Ramirez,

Those warnings will be corrected in the next release, not the current one. Meanwhile you can tweak those lines of code yourself by my suggestion above, or just make sure that your error/warning messages are directed to the PHP log instead of the browser. OJS will continue working fine as long as the warning messages don’t get in your way.
