Session_start(): Failed to read session data: user (path: C:\app\php7.1\tmp) – PHP – Fórum – Programujte.com

Dobrý den, po shlednuti skolo pulky forumu jsem nenašel nic co by mi pomohlo. 
Mam dotaz jak se s tim poprat a popřipadě nějaký řešeni ktere by fungovalo by bylo idealni. 
Děkuji 

Nepolozil jsi dotaz. Nepopsal problem. Nedal zadny php kod.
Servery a prohlizece mivaji ruzna omezeni.
- Povolene cookies?
- Prava k zapisu do adresare pro session?
- Omezeni velikosti diskoveho prostoru adresare session?
- Zkousel jsi pouzit session_regenerate_id? http://php.net/…erate-id.php

session_regenerate_id nepomohlo. 

Aha. Takze chces provozovat Joomlu. Mas ho nainstalovaneho?
Ten kod je jakysi kod ovladajici session. V kodu jsem nenasel nic, jako text 'Failed to read session data', takze si nejsem uplne jisty, zda to vypise php nebo joomla. U session_start, kdyz nenastartuji, tak je tam jiny text. Schvalne jsi dej ctrl+f (vyhledavani v prohlizeci) a najdi si text session_start.
Takze v tuto chvili spis tipuji, ze neni problem se samotnym session_start, ale s tim, ze neco v joomle nefunguje podle ocekavani. Bud neni spravne nainstalovana nebo na tom localhostu nebezi neco spravne.

Na win ted pouzivam Xamp server. Driv jsem pouzival Wamp server. Wamp mi prisel, ze je i lepsi. Kliknes, nainstaluje se, jede. Rucni instalace a spusteni php serveru / apache na win obvykle nedopadne dobre. Na linuxu nevim, tam by se server mel nainstalovat v pohode s snad bez chyb.

Zkus dat do google = Failed to read session data joomla, treba se tam objevi neco chytreho, co by problem resilo.

https://github.com/joomla/joomla-cms/issues/10855
Jestli to spravne chapu, tak tu pisi, ze to souvisi s php7, verze na php 5.6 to pry funguje. Nebo je mozna treba stahnout instalator joomly pro php 5.6.
