Universal ajax live search problem

[perau]

Pozdrav, imam problem sa com_universal_ajax_live_search. Tacnije nece da radi live pretraga. Testirao sam sajt na shared hostingu (cpanel) i sve je OK radilo, kako sam zavrsio migraciju na VPS, pretraga nece da radi, samo vrti u krug. Koristim ovu komponentu samo za pretragu virtuemarta 3. Joomla je 3.6.5

ERROR_LOG:

Taj tvoj com_universal_ajax_live_search je očigledno eksterna i komercijalna komponenta za Joomlu. Nisam to nikad koristila, ali vidim kod njih na sajtu da imaju forum i pomoć za registrovane korisnike.
Na osnovu tvog napisanog, jedino što se odavde vidi je da negde nisi dobro izmenjao putanje za server "GET "http://localhost/index.php?option=co..."
