May you please help me with this guys?

I cannot see the file manager either as a host user or admin user.

The following error is shown in the file manager:

<code><span class="typ">Error</span><span class="pun">:</span> <span class="typ">File</span> <span class="typ">Manager</span> <span class="kwd">is</span> currently unavailable<span class="pun">.</span> <span class="typ">DotNetNuke</span><span class="pun">.</span><span class="typ">ModuleLoadException</span><span class="pun">:</span> <span class="typ">Arithmetic</span> overflow error converting expression to data type <span class="kwd">int</span><span class="pun">.</span> <span class="pun">---></span><span class="typ">System</span><span class="pun">.</span><span class="typ">Data</span><span class="pun">.</span><span class="typ">SqlClient</span><span class="pun">.</span><span class="typ">SqlException</span><span class="pun">:</span> <span class="typ">Arithmetic</span> overflow error converting expression to data type <span class="kwd">int</span><span class="pun">.</span>

</span></code>

Also, when I go to Log Viewer, it shows the following:

Error: Log Viewer is currently unavailable. DotNetNuke.ModuleLoadException: Exception of type System.OutOfMemoryException was thrown. --->System.OutOfMemoryException: Exception of type System.OutOfMemoryException was thrown.--- End of inner exception stack trace ---

I know we can fix it! may you please help me?
