try and add as CUSTOM into Directadmin for the domain:
Code:
<Directory |DOCROOT|/subomain/>
<FilesMatch "\.(inc|php|phtml|phps|php|PHP1_RELEASE|)$">
AddHandler "proxy:unix:/usr/local/php|PHP1_RELEASE|/sockets/|USER|.sock|fcgi://localhost" .inc .php .phtml .php|PHP1_RELEASE|
</FilesMatch>
</Directory>
if you need PHP1 for the
subdomain.
Code:
<Directory |DOCROOT|/subomain/>
<FilesMatch "\.(inc|php|phtml|phps|php|PHP2_RELEASE|)$">
AddHandler "proxy:unix:/usr/local/php|PHP2_RELEASE|/sockets/|USER|.sock|fcgi://localhost" .php|PHP2_RELEASE|
</FilesMatch>
</Directory>
if you need PHP2 for the
subdomain.
Replace the
subdomain with an actual subdomain name.
I did not test it myself.
