“But I don’t understand the error message”

Take a deep breath and try to read the error messages. Some error messages actually have the solution written in them. Look at this one:

Fatal: Automatically populating $HTTP_RAW_POST_DATA is deprecated and will be removed in a 
future version.To avoid this warning set 'always_populate_raw_post_data' to '-1' in php.ini 
and use the php://input stream instead. - in file Unknown - at line 0 [] []

You see the advice in it?

To avoid this warning set ‘always_populate_raw_post_data’ to ‘-1’ in php.ini

But you still don’t know what it means? Simplest thing in this case is to contact your sysadmin and tell them just that.

Let’s Look at some more examples

Error:

PHP Fatal error:  Allowed memory size of 67108864 bytes exhausted (tried to allocate 10924085
 bytes) in ...

Fatal: Maximum execution time of 120 seconds exceeded - in file ...

Solution: This means Adaptix needs more memory / time than your server limit is. Again, contact your sysadmin and consult your possibilities.

Error:

Fatal: Class 'ZipArchive' not found

Solution: It can be ZipArchive, MCrypt or any other PHP module missing. Again, consult you know who to install it.

Error:

PHP Parse error:  syntax error, unexpected T_OBJECT_OPERATOR in

Solution: This usually means your PHP is outdated. Check what the Adaptix requirements are.

Error:

exception 'RuntimeException' with message 'Unable to create the cache directory ...

Solution: It means that the file permissions aren’t right and Adaptix cannot write the cache files.
