Hi, same problem here with latest Uniform Server. [eAccelerator] This build of "eAccelerator" was compiled for PHP version 5.3.2. Rebuild it for your PHP version (5.3.1) or download precompiled binaries. I can solve this modifying the php.ini file: [eaccelerator] ;extension=eaccelerator.dll ;eaccelerator.allowed_admin_path=C:/UniServer/home/admin/www/plugins/eaccelerator/control.php ;eaccelerator.cache_dir=C:/UniServer/tmp/eaccelerator ;eaccelerator.debug = 0 But I still get those errors: PHP Warning: PHP Startup: Unable to load dynamic library 'C:/UniServer/usr/local/php/extensions\\php_mysql.dll' - Impossibile trovare la procedura specificata.\r\n in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library 'C:/UniServer/usr/local/php/extensions\\php_mysqli.dll' - Impossibile trovare la procedura specificata.\r\n in Unknown on line 0 When, of course, those 2 files are present in that directory. Any help?
