error VmConfig::loadJLang

[noe_sp]

hi,
in my page I have this error:

Fatal error: Call to undefined method VmConfig::loadJLang() in /home/a3846938/public_html/modules/mod_virtuemart_category/mod_virtuemart_category.php on line 28

and in my hosting in line 27 and 28 there are:
VmConfig::loadConfig();
VmConfig::loadJLang('mod_virtuemart_category', true );

I do not know what the solution, help please, thanks!
