I don't know how to clear the cache i can't display the admin site. When i go to http://mysite/~mysite/index.php/intranet_admin, the user login interface is displayed, but without any image or css style, and when i want to log in, the system redirects me to the following page :http://mysite/index.php/intranet_admin (which is not the good path);
Whenever an eZ Publish solution is upgraded, all caches must be cleared in a proper way. This should be done from within a system shell:
1.
Navigate into the eZ Publish 3.9.1 directory.
2. Run the clear cache script:
bin/shell/clearcache.sh --clear-all
Please make sure that all caches are cleared. Sometimes the script is unable to clear caches because of restrictive file/directory permission settings. Make sure that all caches have been cleared by inspecting the contents of the various cache subdirectories within the "var" directory.
Alternatively you can clear it by 'brute force' by deleting content inside cache folders in var folder.
