It is advisable to post all the errors as they appear in your error log for this particular issue. Also use preformatted text (CTRL+E) to format the errors for easier readability.
As seen in the second part of your posted logs you might need to disable the ModSecurity CRS Rule Group 911 Method Enforcement rule =>
