WordPress Speed Up Service | WordPress Website Maintenance Packages The request was not found on this server!, by hopefulness Hello I had a Share Hosting and two Domains on it. I bought a VPS service and transferred my Domains and Files from my previous service to new service. although changing DNS, Domains (URLs) didn’t change. I installed MariaDB on VPS. When I want to import my Databases, I see this error: SQL query: CREATE TABLE <code>MPS_commentmeta</code> ( <code>meta_id</code> bigint(20) unsigned NOT NULL AUTO_INCREMENT, <code>comment_id</code> bigint(20) unsigned NOT NULL DEFAULT '0', <code>meta_key</code> varchar(255) COLLATE utf8mb4_unicode_520_ci DEFAULT NULL, <code>meta_value</code> longtext COLLATE utf8mb4_unicode_520_ci, PRIMARY KEY (<code>meta_id</code>), KEY <code>comment_id</code> (<code>comment_id</code>), KEY <code>meta_key</code> (<code>meta_key</code>(191)) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_520_ci; MySQL said: #1273 - Unknown collation: 'utf8mb4_unicode_520_ci' I replaced CHARSET from utf8mb4 to utf8 and COLLATE from utf8mb4_unicode_520_ci to utf8_general_ci Than, I could import previous database to phpMyAdmin. Now one of my site works well. The other one has a problem. the site loads the home page but does not find any pages. Not Found The requested URL ... was not found on this server.
