TYPO3: SQL error: 'Incorrect integer value: '' for column 'sys_language_uid' at row 1'
I have newly setup TYPO3, but when I try to add/save content, it gives me this error: SQL error: 'Incorrect integer value: '' for column 'sys_language_uid' at row 1 The behavior is related to database management systems using strict mode, like MySQL since version 5.7. Disabling strict mode (like provided in the accepted answer) is just a work around. The real solution would be to explicitly cast values to integer by modifying TCA (table configuration array) for the according field definitions. for fields of type input that would be setting/extending 'eval' => 'int' , see example tt_content
