"-1" in search result dropdown

I still struggle with this plug in. It continues to respond as detailed above. Any suggestion on a fix OR is there an alternative plug in I can use and just delete this one?

I’m still seeing this problem on my site.

This is a page caching problem I believe and probably explains why a shift+refresh resolves the issue. The “-1” is an Ajax Error. If you have any sort of page caching enabled or page caching plugins then I would start by disabling that and seeing if it fixes the problem.

For me, I had page caching enabled in .htaccess like so:

## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg “access 1 year”
ExpiresByType image/jpeg “access 1 year”
ExpiresByType image/gif “access 1 year”
ExpiresByType image/png “access 1 year”
ExpiresByType text/css “access 1 month”
ExpiresByType application/pdf “access 1 month”
ExpiresByType text/x-javascript “access 1 month”
ExpiresByType application/x-shockwave-flash “access 1 month”
ExpiresByType image/x-icon “access 1 year”
ExpiresDefault “access 2 days”
</IfModule>
## EXPIRES CACHING ##

So what I did was excluded .php files from caching like this and the “-1” bug seems to have gone away:

## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg “access 1 year”
ExpiresByType image/jpeg “access 1 year”
ExpiresByType image/gif “access 1 year”
ExpiresByType image/png “access 1 year”
ExpiresByType text/css “access 1 month”
ExpiresByType application/pdf “access 1 month”
ExpiresByType text/x-javascript “access 1 month”
ExpiresByType application/x-shockwave-flash “access 1 month”
ExpiresByType image/x-icon “access 1 year”
ExpiresDefault “access 2 days”

<FilesMatch “\.(php|cgi)$”>
ExpiresActive Off
</FilesMatch>

</IfModule>
