Hi Guys,

I have a BIG problem with my site. The site views fine to the outside world but when I go to the admin panel I get and error page presented to me - see below error code:
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
[User Error] Bad class to singleton() - AccountPage
GET /admin

Line 263 in /homepages/xx/xxx/htdocs/sapphire/core/Core.php
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

254    if(($pos = strpos($className,'_')) !== false) $className = substr($className,0,$pos);
255    if($_CLASS_MANIFEST[$className]) return $_CLASS_MANIFEST[$className];
256 }
257
258 function singleton($className) {
259    static $_SINGLETONS;
260    if(!isset($className)) user_error("singleton() Called without a class", E_USER_ERROR);
261    if(!is_string($className)) user_error("singleton() passed bad class_name: " . var_export($className,true), E_USER_ERROR);
262    if(!isset($_SINGLETONS[$className])) {
263     if(!class_exists($className)) user_error("Bad class to singleton() - $className", E_USER_ERROR);
264       $_SINGLETONS[$className] = Object::strong_create($className,null, true);
265       if(!$_SINGLETONS[$className]) user_error("singleton() Unknown class '$className'", E_USER_ERROR);
266    }
267    return $_SINGLETONS[$className];
268 }
269

I am using version 2.3.1

Any ideas?

Thank you

[User Error] Bad class to singleton() - AccountPage

It means that the database or the cache is out of date. Its trying to access the AccountPage before its in the cache. Have you added any functionality recently? You might need to do a dev/build?flush=all then reload the admin.

Thanks Will - that fixed it. I removed an e-commerce module and forgot to do the dev/build subsequently.
