Has anyone see then before?
Warning: set_error_handler() expects the argument (_exception_handler) to be a valid callback in /home/nginx/domains/xxx.com/ee_core/codeigniter/system/core/CodeIgniter.php on line 63
Fatal error: Call to undefined function is_php() in /home/nginx/domains/xxx/ee_core/codeigniter/system/core/CodeIgniter.php on line 65
Since last night, all URLs on the site suddenly started returning that message. I can't access the CP, either. From looking at the code in CodeIgniter.php, it looks like the missing functions are all in Common.php, which is included at the top of the file. Any reason CI would be unable to run the included code? (Yes, I checked permissions already....)
Any help is greatly appreciated!
