There is no entry in the $TCA array for the table "your_unknown_table"

Exception 1283790586 'There is no entry in the $TCA array for the table "your_unknown_table". This means that the function enableFields() is called with an invalid table name as argument.'

This exception is thrown in TYPO3\CMS\Frontend\Page\PageRepository::enableFields when the table (as mentioned in the error) is not found in the TCA.

Possible causes

Your project uses:

PHP-code with enableFields('your_unknown_table').
TypoScript-code with an unknown table in a CONTENT-object. There might be an indication of this in the backtrace, f.e. TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer::cObjGetSingle("CONTENT", array, "30") indicates that an unknown table is used in a CONTENT element with the name '30'.
Backtrace is the detailed error output when dev mode is enabled in the install tool. I searched it for "array" and found this: TypoScript Code TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer::cObjGetSingle("TEMPLATE", array, "100"). Now I searched my templates for the string "100". It was the main page template, and I found some temp. objects that were defined as temp.myobject = CONTENT, but due to some conditions, in some cases, had no further definition. TYPO3 4.5 could live with that, 6.2 threw an error.

Bad:

temp.item = CONTENT
[globalVar = LIT:1 = {$constant}]
temp.item {
}
[global]

Less bad:

temp.item =
[globalVar = LIT:1 = {$constant}]
temp.item =CONTENT
temp.item {
}
[global]
