[Plugin: WP Maintenance Mode] Just get "The service is unavailable." when not logged in

Current i have tested in WP 3.3 and 3.4. no problems; works fine.
You have install all files?

I’m getting the same message. The maintenance page doesn’t show up, no matter what theme I choose from the list. All I get is that 503 error.

And when I’m logged in on WordPress for iOS I get the same 503 message which means I can’t log in there.

but maybe you have an other plugin with an rewrite or htaccess?
the plugin create an rewrite to the maintenance page, if is active.

I am also having the same issue.

iansml and Naz, are you hosting on a Linux server or Windows/IIS?

jh

Sorry for the late response. I am using a different plugin now. But I’m using Windows hosting. I hope that helps. ??

In case anyone stumbles on this before finding a solution,

If you are using a Windows IIS webserver this should do the trick.

Using IIS 7.x with the MS URL Rewriter installed (https://www.iis.net/downloads/microsoft/url-rewrite)
And PHP for your site running in FastCGI mode.

Then you need your web.config file in your site’s home directory to contain these details:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
      <rules><rule name="Main Rule" stopProcessing="true"><match url=".*"/><conditions logicalGrouping="MatchAll"><add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true"/><add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true"/></conditions><action type="Rewrite" url="index.php"/></rule>
				<rule name="wordpress" patternSyntax="Wildcard">
					<match url="*"/>
						<conditions>
							<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true"/>
							<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true"/>
						</conditions>
					<action type="Rewrite" url="index.php"/>
				</rule></rules>
    </rewrite>
		<httpErrors errorMode="Detailed" />
    </system.webServer>
</configuration>

If you are still using IIS6 then a similar solution will work but you would need a Third Pary URL rewriting ISAPI module for the functionality usually given with Apache/ModRewrite in .htaccess
