Hi, I'm using plesk with apache and wordpress and having trouble with installing or updating plugins. After every install through the wordpress admin i get the error "install failed: could not copy file", when updating i also get errors about zip files. The tech team have checked and the permissions are correct, but is there anything that could happen with ownership as it is a shared server? Are the permissions different for a shared server? Also the plugins do install and can be seen as installed on the dashboard and they do update, but all with errors.
