We are using TYPO3 8.7.19 with the extension frontend_editing (Version: 1.4.0) and CoolURI. We still use css_styled_content.
When editing a content element in the frontend with the „frontent-editing bar”, e.g. text I get an error, but only, if it contains an internal link. The changes are not saved. It crash with:
Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1460629247: No valid handlers found for type: unknown | TYPO3\CMS\Core\LinkHandling\Exception\UnknownLinkHandlerException thrown in file /usr/share/typo3/typo3_src-8.7.19/typo3/sysext/core/Classes/LinkHandling/LinkService.php in line 163. Requested URL: https://www.mysite.de/typo3/index.php?ajaxID=%2Fajax%2Ffrontend-editing%2Fprocess&ajaxToken=--AnonymizedToken--&page=123
There is a bug report and a suggested solution für TYPO3 9.5.x and a solution for TYPO3 8.7.x
Unfortunately, I don't know how to realize that solution for my system, cause
Any hints for me?
Problem has been solved by the author of frontend_editing:
Add in typo3conf/ext/frontend_editing/Configuration/TypoScript/setup.ts
# Prevent links from being parsed to FE url
