Server error 500 PHP Startup: Unable to load dynamic library

We developed a site on a PC and loaded all the files to the server via FTP. We are getting a server error 500. We are running PHP Version 5.4.43 on The main site on the server is running wordpress. The server is setup that all extra domains are in subfolders. MAIN-DOMAIN/public_html/ADDON-DOMAIN/

This is from the error log:
Warning: PHP Startup: Unable to load dynamic library ‘/usr/php/54/usr/lib64/php/modules/’ - /usr/php/54/usr/lib64/php/modules/ undefined symbol: zend_new_interned_string in Unknown on line 0

PHP Notice: Use of undefined constant DIR - assumed ‘DIR’ in /home1/mydomain/public_html/mysubfolder/index.php on line 6

PHP Warning: require(DIR/kirby/bootstrap.php) [function.require]: failed to open stream: No such file or directory in /home1/mydomain/public_html/mysubfolder/index.php on line 6

PHP Fatal error: require() [function.require]: Failed opening required ‘DIR/kirby/bootstrap.php’ (include_path=’.:/usr/php/54/usr/lib64:/usr/php/54/usr/share/pear’) in /home1/mydomain/public_html/mysubfolder/index.php on line 6

What can we do to fix this?

Never mind it just started working all of a sudden. Ask for tech support just as things fix themselves.

Well, sounds as if the upload had not finished when you opened the site in a browser:wink:
