Algunos temas o mejor dicho paginas de un tema NO se ven cuando estoy conectado/logeado en el foro.... pero cuando no estoy conectado se ven perfectamente... me refiero a que no se ve por que marca error 500.

Si el tema tiene 6 paginas sin conectar, conectado solamente indica que son 3 paginas...
Conectado, solo veo la ultima pagina, y las 2 primeras me marca el error: Este error (HTTP 500 Error interno del servidor) significa que el sitio web al que está conectado tiene un problema con el servidor que impide que se muestre la página web.

Ya revise logs y no encuentro nada raro.

normalmente esos errores (500) tienen que ver con los permisos de los archivos o con al configuración de .htaccess

Pero que ves en el logs? Sabes leerlos? Hace la prueba de ingresar a donde te sale error y ahí mismo fijarte en el logs; tus usuarios te han reportado el mismo problema?

Antes que nada, MUCHISIMAS GRACIAS por su ayuda...
El .htaccess ya tiene bastante tiempo que no se modifica (desde que instale la ultima versión de Google SEO)... de hecho el foro tiene bastante tiempo que no le agregaba ningún plugin y estaba funcionando bien... el ultimo cambio fue una actualización de tapatalk hace como 1 mes... y esto empezó hace como una semana y no es con todos los temas es solo con algunos...

Desde el panel de administración me sale que "All of the required files and directories have the proper CHMOD settings"

y esto es lo que me sale en los logs:

Ya arregle lo del avatar, pero aun no doy que esta pasando. Saludos.

No, eso no son los errores que buscamos, fijate de ingresar en el cPanel e ir a una opción de Registro de errores, algo así debe decirte, pasa que varia el lenguaje según el cual haya elegido tu proveedor. Por eso busca algo de registro de errores, en él te mostrará todos los errores que tenés; es diferente al error.log que esta en el FTP pero por las dudas fijate en todo.

Otra opción que puede demorar, es pedirle a tu proveedor que mire los errores de tu cuenta de apache. Capas sea algo sencillo y nosotros ni cuenta xD

Intenta, reparar y optimizar las tablas de tu BD.

Este es el log... pero no logro identificar el error

por lo que veo parece que te faltan algunos archivos o la web no los encuentra donde debieran estar

Según el ultimo log que dejas citado, el problema es que esta buscando archvios en una web que "no existe"

Al menos en tus datos de usuario, tu web indica que es zonareef.com, en los logs claramente esta buscando las cosas en otro dominio, vos cambiaste de dominio?, tenias algún alias o dominio aparcado?

Pues encontre unos errores en el .htaccess, ya los corregi (por eso lo del miwebx)... actualize de version a la 1.6.14 comenzo a funcionar bien... de repente, nuevamente volvio a fallar.... asi que cambie en el php.ini los valores de display error a on y log_errors = On... ya con esto ahora si estoy viendo el error:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /srv/disk3/631425/www/zonareef.com/inc/functions_post.php(603) : eval()'d code on line 2

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /srv/disk3/631425/www/zonareef.com/inc/functions_post.php(603) : eval()'d code on line 2

Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 279171 bytes) in /srv/disk3/631425/www/zonareef.com/inc/plugins/tapatalk.php on line 655

Esto es lo que tiene en la linea 603 (functions_post.php):
$cache->update_forums();

Y esto es lo que tiene el tapatalk.php en las lineas 655 y 656:
$page = str_ireplace("</head>", $str . "\n</head>", $page);
$page = preg_replace("/<body>/isU", "<body>\n".$tapatalk_smart_banner_body, $page,1);

Actualiza el sistema de TapaTalkl y reinstala el archivo inc/functions_post.php
