I first installed it manually and it didn’t work (as mentioned in the previous comment). I’m now trying to install it using the Plugin Gallery in OJS and it shows me this message:
“Plugin was not successfully copied. This may be a permissions problem. Please make sure that the web server is able to write to the plugins directory (including subdirectories) but don’t forget to secure it again later.”
My plugin directory inside the ojs installation have permission 0777 as well as every sub directory, my php server api is “Apache 2.0 Handler”, do you know how can I fix this error?
