Ok, will take this slowly ... one at a time:
Investigate this warning first:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modulenown on line 0
What does your server have in /usr/lib64/php/?
Typically (normally) there is a 'module' directory located in /usr/lib64/php/ .... what is 'modulenown' and how did it ge there? Is it a directory? If so what is in the directory?
