Ya tocaba. Realizo la pertinente copia de seguridad, cambio la versi\u00f3n de MySQL, convierto las tablas de UTF8 a utf8mb4 para que puedan contener \u00abemojis\u00bb, habilito en el servidor la versi\u00f3n recomendada de PHP (7.4) que de las otras ya no hay soporte, ejecuto el script de actualizaci\u00f3n y cruzo los dedos (lo de aguantar la respiraci\u00f3n, paso, que le lleva 10min…) TODO OK!<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Hasta que descubres que las im\u00e1genes de resumen de los cursos , las fotos de tus repositorios de preguntas y alg\u00fan que otro elemento ahora ya no se muestra. Vale. Que no cunda el p\u00e1nico…..<\/p>\n\n\n\n\n\n\n\n

Veamos:<\/p>\n

    \n
  1. Revisando permisos en la carpeta de archivos….. todo OK.<\/li>\n
  2. Revisando los registros en la base de datos, comparando los \u00abhash\u00bb y localizando el documento original….Pues s\u00ed, est\u00e1n ah\u00ed.<\/li>\n
  3. Cambiando de \u00abtema\u00bb visual….. Nada, sigue igual.<\/li>\n
  4. \u00bfProblema al migrar las tablas? \u00bfSe ha producido alguna actualizaci\u00f3n de las URLs? No deber\u00eda. Veamos el c\u00f3digo HTML del objeto que no se muestra….<\/li>\n<\/ol>\n
    https:\/\/diocesanos.es\/moodle\/pluginfile.php\/13019\/course\/overviewfiles\/tic.jpg<\/pre>\n
    … y con la versi\u00f3n anterior era algo as\u00ed como:<\/p>\n
    https:\/\/diocesanos.es\/moodle\/pluginfile.php?file=<\/strong>\/13019\/course\/overviewfiles\/tic.jpg<\/pre>\n
    YA ESTA!<\/strong> Al realizar la actualizaci\u00f3n se ha abilitado por defecto la opci\u00f3n \u00abslasharguments\u00bb. Vamos a la configuraci\u00f3n del servidor de moodle y….<\/p>\n\n\n\n
    \"\"<\/a><\/figure>\n\n\n\n
    O ser\u00e1 la rev\u00e9s. Qu\u00e9 pasar\u00e1 si la activo…. DESASTRE<\/strong>! Adi\u00f3s a los estilos CSS y a todas las im\u00e1genes (por lo menos).<\/p>\n\n\n\n
    NOTA<\/strong>: el servidor linux de 1and1 \/ Ionos\u00a0 NO soporta<\/strong> el uso de \u00abslasharguments\u00bb de ninguna forma (al menos por ahora), y no puede habilitarse mediante archivos \u00ab.htaccess\u00bb<\/em><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
    No existe opci\u00f3n, par\u00e1metro o ajuste en la configuraci\u00f3n de Moodle, del servidor (las que me dejan tocar) o del sistema de archivos que muestre como antes (v3.5)\u00a0 las im\u00e1genes que \u00abhan desaparecido\u00bb (y las he probado todas).<\/p>\n
    \u00abGoogleando\u00bb un poco descubro que el problema comienza precisamente al actualizar la versi\u00f3n 3.5 en adelante, y se da principalmente en instalaciones con 1and1…..pero nadie da una soluci\u00f3n satisfactoria…hasta que llego a un post [MDL-28538]<\/a> <\/strong>que hace referencia a un \u00aberror\u00bb y propuesta de correcci\u00f3n sobre el uso de la variable \u00abPATH_INFO\u00bb del servidor… o eso intenta porque dicha variable nunca llega a definirse!<\/p>\n
