Have you take a look via FTP at the folder to the permissions are set there? * When at the three other hostings the settings are set properly by the plugin, you should take a look on this one hoster. * Is the folder empty or are the gravatars chached there? * Best regards, Harry * Thread Starter [eldarius](https://wordpress.org/support/users/eldarius/) * (@eldarius) * [10 years, 5 months ago](https://wordpress.org/support/topic/problem-149/#post-6883589) * Yes, i set 755, i am pretty sure, i can show a screenshots. i tried on 3 different hostings * Plugin Author [Harry Milatz](https://wordpress.org/support/users/harry-milatz/) * (@harry-milatz) * [10 years, 5 months ago](https://wordpress.org/support/topic/problem-149/#post-6883591) * what do you mean with different hostings? you have three sites(three domains) with different contents on three different hosters and you get the on all hosters the same notice? * Can you give me the URLs to your sites? * Of course, screenshots could be helpful. * Best regards, Harry * Thread Starter [eldarius](https://wordpress.org/support/users/eldarius/) * (@eldarius) * [10 years, 5 months ago](https://wordpress.org/support/topic/problem-149/#post-6883592) * give me your email please * Plugin Author [Harry Milatz](https://wordpress.org/support/users/harry-milatz/) * (@harry-milatz) * [10 years, 5 months ago](https://wordpress.org/support/topic/problem-149/#post-6883593) * harry[aet]all4hardware4u.de * Thread Starter [eldarius](https://wordpress.org/support/users/eldarius/) * (@eldarius) * [10 years, 5 months ago](https://wordpress.org/support/topic/problem-149/#post-6883594) * done. let me know if u login * Plugin Author [Harry Milatz](https://wordpress.org/support/users/harry-milatz/) * (@harry-milatz) * [10 years, 5 months ago](https://wordpress.org/support/topic/problem-149/#post-6883598) * ok, i have logged in and take a look. I think the plugin is not able (not allowed) to write the settings in the database. Can you take a look via phpMyAdmin and look at the table “your_prefix_harrys_gravatar_cache” ? There should be something like in the screenshot i sent you via mail. * Plugin Author [Harry Milatz](https://wordpress.org/support/users/harry-milatz/) * (@harry-milatz) * [10 years, 5 months ago](https://wordpress.org/support/topic/problem-149/#post-6883604) * Ok i see in your screenshot that the database table is empty. That shouldn’t be. * Is there something to see in the errorlog why the table couldn’t be filled with the “options” by the plugin? * Try to deactivate and deinstall the plugin. Then the table should be deleted. If not so delete it after deinstalling the plugin manually. * Then install the plugin via your backend again and take a look in the database table. * Thread Starter [eldarius](https://wordpress.org/support/users/eldarius/) * (@eldarius) * [10 years, 5 months ago](https://wordpress.org/support/topic/problem-149/#post-6883606) * Done. Result is the same. * Thread Starter [eldarius](https://wordpress.org/support/users/eldarius/) * (@eldarius) * [10 years, 5 months ago](https://wordpress.org/support/topic/problem-149/#post-6883607) * But i noticed after activation this error * The plugin generated 285 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin. * Plugin Author [Harry Milatz](https://wordpress.org/support/users/harry-milatz/) * (@harry-milatz) * [10 years, 5 months ago](https://wordpress.org/support/topic/problem-149/#post-6883617) * ok, that is the reason why the table is empty. i will do a fallback in the next update that the message in the settings-page is clear when the database table couldn’t be filled. * there are some more errors for the plugin “dl-yandex-metrika” if you look at your dashboard. it seems that another plugin is responsible for this errors. try to deacticate one plugin by the other and check if the errors are gone. * After this try to reinstall the plugin here again. * And be careful of plugins that are not supported for WP 4.4 like “jQuery Smooth Scroll”, this is supported til 4.1.8 * Thread Starter [eldarius](https://wordpress.org/support/users/eldarius/) * (@eldarius) * [10 years, 5 months ago](https://wordpress.org/support/topic/problem-149/#post-6883619) * the result is the same. I created new wp site on another hosting – same problem. I have only one plugin installed * Plugin Author [Harry Milatz](https://wordpress.org/support/users/harry-milatz/) * (@harry-milatz) * [10 years, 5 months ago](https://wordpress.org/support/topic/problem-149/#post-6883620) * wow that is very fast to crate another new wp site on a new hoster.;) * that is really strange. is the other hosting(the new wp site) the same hoster or another one? * can you add this to your wp-config.php `define('WP_DEBUG', true);` and take a look in the errorlog file in your wp-content folder after reinstall the plugin? * the message “The plugin generated 285 characters of unexpected output during activation” is most shown if any whitespace or lines are after the closing php- tag or the last line in the plugin-file, but that isn’t so in my plugin. * Thread Starter [eldarius](https://wordpress.org/support/users/eldarius/) * (@eldarius) * [10 years, 5 months ago](https://wordpress.org/support/topic/problem-149/#post-6883668) * I did it – there was nothing about your plugin. * Plugin Author [Harry Milatz](https://wordpress.org/support/users/harry-milatz/) * (@harry-milatz) * [10 years, 5 months ago](https://wordpress.org/support/topic/problem-149/#post-6883684) * is there anything about an error?
