A website was reported to quit working and that was true. All other websites on the machine (about 50) had no problem. Figured they screwed something up. Restored it to a backup from yesterday, then last week. Same results. Restored to two other machines and received the error: One server was just built a few days ago, the other about a month. New machines with no known problems.
Your PHP installation appears to be missing the MySQL extension which is required by WordPress.
Apache error log does not have a lot in it. The only critical error: [Mon Mar 03 22:24:07 2014] [crit] [client 220.127.116.11] (13)Permission denied: /home/prospectorman/public_html/wp-admin/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable
Not even an error generated when I was trying to display the website. Very little in the logfiles. My guess is that the error message about the MySQL extension is not the real problem. So what could the real problem be and how to I figure that out? Logfiles is the only thing I can think of at the moment. There is a long string of errors in the /etc/httpd/logs/error_log such as:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/mcrypt.so' - /usr/lib/php/modules/mcrypt.so: cannot open shared object file: No such file or directory in Unknown on line 0
This is true for php/modules/mysql.so php/modules/mysqli.so php/modules/odbc.so php/modules/pdo.so and several others. However, all sites on the servers are working except this one.
