Sometime you may experience the following error after the installation:

2015-06-23 14:29:56.297	ERROR	[config:scripthandler] Can not find handler with type: 12, name: lsphp72.
2015-06-23 14:29:56.297	ERROR	[config:scripthandler] Can not find External Application: lsphp72, type: lsapi
2015-06-23 14:29:56.297	ERROR	[config:scripthandler] use static file handler for suffix [php72]

It simply means no lsphp72 external application set up yet. You should create an external app lsphp72 and point a right binary to it.

Most likely you won't see such error since most of the PHP handler have been preconfigured. If some occasion, newer version of PHP, such as lsphp72 or a future version, may not be included in LSWS configuration, you can manually create such lsphp72 external app and point it to ea-php72-lsphp binary, or CL php72 binary when CloudLinux is used.

In cPanel EA3 environment, LiteSpeed normally builds matching PHP most likely for 5.4.x hence no lsphp55 installed.

The message itself is absolutely safe to be ignored. If you just like to get rid of the error, you can do either of the following:

• Install lsphp55 and pointing the /usr/local/lsws/fcgi-bin/lsphp55 to the newly installed binary.
• Simply remove lsphp55 handler.
• Use any exiting PHP handler as lsphp55, for example:

 ln -sf /usr/local/lsws/fcgi-bin/lsphp5 /usr/local/lsws/fcgi-bin/lsphp55

The last one creates a symbolic link to use lsphp5 as lsphp55 handler. It is not recommended, though it can remove the error alert, since faked lsphp55 may create misunderstanding in the future.
