Table keeps having error "a <box> was supposed to be here" [closed]

Question

Everytime I set a table's position to [H], an error appears saying "A <box> was supposed to be here". The table fits the page and everything appears to be fine, except for the errors. If I change the position of the table the error disappeares but I want the table exactly at that place.

My table code is like this:

\begin{table}[H]
\centering
\caption{Types of accounts and their permissions}
\label{table:accounts}
\begin{tabularx}{\textwidth}{|X|X|X|}
 %content
\end{tabularx}
\end{table}
