Joomla PHP error in page content

Question

Warning. Parameter 3 for showBlogSection () must be a link, the value is specified in / home / smartsta / public _html / includes / Cache / Lite / Function.php on line 100

I get the above error in my content areas on my Joomla site all of a sudden, any suggestions?

Update: Cannot find access to a specific file and directory in the file directory godaddy ftp, ftp or Joomal C-panel. Within FTP, I cannot find access to this particular file to find out what is on line 100. In the Joomla panel in Global Configurations, I was able to disable the error message "none" because this error is not hidden. Inside the cache directory, I do not see any parameters for accessing the folder, although it is displayed. I also see this at the bottom of the c-panel screen, but just links to the joomla help site, and within the fields I do not see the described area for switching "ON" or "OFF", "The following PHP Server settings are not optimal for security, and they recommended change: Setting PHP register_globals ON instead of OFF "

Update2:

I found the file in question, below is the code. Line 100 defines only:

global $$ object_123456789;

This is not quite a mistake. This is a warning .

all of a sudden? You may have updated / updated your version of PHP. Or changed the configuration of PHP to "strict mode".

The message " , which is expected to be a link, value ), means that the called function should receive the link , not the value . See:

 $something = 9; show_section($something); // here you are passing a variable // this will be accepted as a reference show_section(9); // here you are NOT passing a reference // here you are passing a VALUE 

When you pass "by reference", the function can change the value of the variable ... in the above example:

 function show_section(&$parameter) { $parameter = 'changed!'; } 

• Pay attention to the ampersand symbol & before $parameter - this is how we specify the function, a link is required.

• AFTER the function call, in the above example, the value of the $something variable will be changed! .

The error throwing line is NOT "global." This is the following:

 $result = call_user_func_array(array($$object_123456789, $method), $arguments); 

The problem here is that the function is called indirectly using the call_user_func_array function.

The solution will convert all arguments to links. Sentence:

 foreach ($arguments as $count => $value) { $param = 'param' . $count; $$param = $value; $arguments[$count] = &$$param; } 

Put the code above at the beginning of the call function, on the right after the following line:

 $id = serialize($arguments); 

Give it a try!
