Kao \u0161to sigurno znate W3 Total Cache je prili\u010dno dobar kada je u pitanju alat sa mnogo pode\u0161avanja za WordPress caching. W3 Total Cache generi\u0161e stati\u010dki cache page za svaku stranu koja se u\u010ditava dinami\u010dki i time znatno pove\u0107ava brzinu u\u010ditavanje stranice i pobolj\u0161ava preformanse.<\/div>\n

Ukoliko koristite ili planirate da po\u010dnete da koristite njegove pogodnosti budite svesni toga da postoji velika verovatno\u0107a da \u0107ete dobiti gre\u0161ku 500 Internal Server Error. Naravno mo\u017ee da bude vi\u0161e razloga za to. Me\u0111utim ovde ima par stvari kako da na\u0111ete i kako ono jo\u0161 va\u017enije kako da popravite ukoliko dobijate tu gre\u0161ku.<\/p>\n

Prva stvar morate da proverite .htaccess fajl da vidite da li je W3 Total Cache dodat u sam fajl, tj na dnu samog fajla. Na primer treba da izgleda ovako:<\/p>\n

<IfModule mod_rewrite.c>
\nRewriteEngine On
\nRewriteBase \/
\nRewriteRule ^index\\.php$ \u2013 [L]
\nRewriteCond %{REQUEST_FILENAME} !-f
\nRewriteCond %{REQUEST_FILENAME} !-d
\nRewriteRule . \/index.php [L]
\n<\/IfModule># BEGIN W3TC Browser Cache
\n<IfModule mod_deflate.c>
\n<IfModule mod_setenvif.c>
\nBrowserMatch ^Mozilla\/4 gzip-only-text\/html
\nBrowserMatch ^Mozilla\/4\\.0[678] no-gzip
\nBrowserMatch \\bMSIE !no-gzip !gzip-only-text\/html
\nBrowserMatch \\bMSI[E] !no-gzip !gzip-only-text\/html
\n<\/IfModule><\/p>\n

Primeti\u0107ete liniju gde je:<\/p>\n

<\/IfModule># BEGIN W3TC Browser Cache<\/p>\n

Ovo je u stvari ono \u0161to pouzrokuje gre\u0161ku. „# BEGIN W3TC Browser Cache“ treba da se nalazi u novoj liniji. Re\u0161enje? Jednostavno samo pre tarabe pritisnite enter i sa\u010duvajte.<\/p>\n<\/div>\n

Za\u0161to se ovo uop\u0161te desilo pre svega?<\/p>\n

Normalna WordPress instalacija kreira sam fajl .htaccess. WordPress rewrite code izgleda ovako:<\/p>\n

\n

# BEGIN WordPress
\n<IfModule mod_rewrite.c>
\nRewriteEngine On
\nRewriteBase \/
\nRewriteRule ^index\\.php$ \u2013 [L]
\nRewriteCond %{REQUEST_FILENAME} !-f
\nRewriteCond %{REQUEST_FILENAME} !-d
\nRewriteRule . \/index.php [L]
\n<\/IfModule>
\n# END WordPress<\/p>\n

W3 Total Cache izgleda da tra\u017ei u fajlu komentar „# BEGIN WordPress“, tako on zna kada da doda ostale linije koda. Me\u0111utim ukoliko je htaccess fajl izmenjen i ovaj komentar ne postoji W3 Total Cache ne zna \u0161ta da radi. W3 Total Cache dodaje svoje kodove na kraju samog fajla. Ukoliko imate „# END WordPress“ liniju nije neki problem, W3 TotalCache \u0107e dodati iznad tog komentara i to ne\u0107e imati nikakav uticaj na Apache.<\/p>\n

Problem nastaje ukoliko ne postoje komentari i ne postoje nove linije ve\u0107 je sve u jednom redu. Apache \u0107e prijaviti 500 gre\u0161ku jer \u0107e W3 dodati kod na poslednjoj liniji u svakom slu\u010daju bez obzira \u0161ta pi\u0161e.<\/p>\n
