Smarty warnings from core.get_include_path.php

• Error

Error using Tiki 5.3 on a shared hosting (installed in …/httpdocs/tiki). This error does not occur with TikiWiki 4.1 on the same hosting (installed in …/httpdocs/tiki4).

When I try (as admin) to edit users in Tiki 5.3, I get these PHP errors:
PHP (5.2.9) ERROR (E_WARNING):

Line: 34

To me it seems that the open_basedir restriction is reasonable (my hosted Web space + /tmp). There seems to be a syntax error (beginning / before lib) inducing a confusion between /lib on the server and the …/httpdocs/tiki/lib folder in my installation. (By the way, I do not understand // in the path.)

I tried to read line 34 in core.get_include_path.php, but I am not a programmer and I cannot figure how to correct the syntax error. I do not know the value of all these variables at the moment the function is called.

Could somebody suggest a correction or a workaround?

The Smarty warnings remain, but workaround found.
(The 5.3 admin users bug - see comments - was fixed in 5.4.)
