Hi,

After installing 3.8.3 on J3.10 I got a 500 Internal Server Error when doing a request that should be giving 404 errors. After I put the Error Reporting on Maximum I encountered the following error:

Fatal error: Uncaught Exception: Page not found in [path]public_html/components/com_sppagebuilder/router.php:110 Stack trace: #0 [path]public_html/components/com_sppagebuilder/router.php(172): SppagebuilderRouterBase::parseRoute() #1 [path]public_html/libraries/src/Component/Router/RouterLegacy.php(105): SppagebuilderParseRoute() #2 [path]public_html/libraries/src/Router/SiteRouter.php(438): Joomla\CMS\Component\Router\RouterLegacy->parse() #3 [path]public_html/libraries/src/Router/Router.php(482): Joomla\CMS\Router\SiteRouter->parseSefRoute() #4 [path]public_html/libraries/src/Router/Router.php(227): Joomla\CMS\Router\Router->_parseSefRoute() #5 [path]public_html/libraries/src/Router/SiteRouter.php(139): Joomla\CMS\Router\Router->parse() #6 /home/[path]/ak in [path]public_html/components/com_sppagebuilder/router.php on line 110

I must say we are using SH404SEF, although in this case I see no reference to this component, so it could be isolated to this issue.

In the changelog I see some references to the router in 3.8.3, so I guess this is where the issue arose. After downgrading to 3.8.2 the issue was resolved.
