Probleme nach Umzug Installation unter 4.9

[Gruematz]

Hallo,

ich brauche dringend Hilfe. Ich habe eine Installation auf eienn neuen Server umgezogen, was soweit alles geklappt hat, Contao-Manager meckert nicht, Backend geht, Vorschau führt zu Fehler:

[2023-03-22 17:20:05] request.INFO: Matched route "tl_page.2629". {"route":"tl_page.2629","route_parameters":{"_toke n_check":true,"_controller":"Contao\\FrontendIndex ::renderPage","_scope":"frontend","_locale":"de"," pageModel":"[object] (Contao\\PageModel: {})","parameters":"","_route":"tl_page.2629"},"req uest_uri":"http://ivf-hh.de.www480.your-server.de/preview.php/kinderwunsch-hormone-hamburg.html","method":"GET"} []

[2023-03-22 17:20:05] security.INFO: Populated the TokenStorage with an anonymous Token. [] []

[2023-03-22 17:20:05] request.CRITICAL: Uncaught PHP Exception Symfony\Component\ErrorHandler\Error\ClassNotFound Error: "Attempted to load class "SEO" from namespace "PCT". Did you forget a "use" statement for another namespace?" at /usr/www/users/ivfshh/templates/layout/j_accordion.html5 line 4 {"exception":"[object] (Symfony\\Component\\ErrorHandler\\Error\\ClassNot FoundError(code: 0): Attempted to load class "SEO" from namespace "PCT".\nDid you forget a "use" statement for another namespace? at /usr/www/users/ivfshh/templates/layout/j_accordion.html5:4)"} []

Ich weiß nicht, was ich machen kann, damit die Installation auf dem neuen Server läuft. Der bisherige ivf-hh.de.

Stelle gerne Zugangsdaten zur Verfügung.

Danke

Möglicherweise hast Du beim Umzug etwas vergessen?

Nach der Meldung

[2023-03-22 17:20:05] request.CRITICAL: Uncaught PHP Exception Symfony\Component\ErrorHandler\Error\ClassNotFound Error: "Attempted to load class "SEO" from namespace "PCT". Did you forget a "use" statement for another namespace?" at /usr/www/users/ivfshh/templates/layout/j_accordion.html5 line 4 {"exception":"[object] (Symfony\\Component\\ErrorHandler\\Error\\ClassNot FoundError(code: 0): Attempted to load class "SEO" from namespace "PCT".\nDid you forget a "use" statement for another namespace? at /usr/www/users/ivfshh/templates/layout/j_accordion.html5:4)"} []

liegt das nahe. Irgendeine Spezialität, die Dir "Premium Contao Themes" beschert hat?
