Problem with PageSpeed Ninja plugin after installing “mod_pagespeed”

Hello,
since I installed the “mod_pagespeed” module on my VPS with apache I have problems with your (fantastic) plugin.
I also installed the “Fixes for mod_pagespeed” plugin.
I have no active cache cache.
I have this problem ONLY with the mobile version of the site. Also in “Safe” mode.

Here is the configuration of my ModPagespeed:

<IfModule pagespeed_module>
ModPagespeed on
AddOutputFilterByType MOD_PAGESPEED_OUTPUT_FILTER text/html
ModPagespeedFileCachePath            "/var/cache/mod_pagespeed/"
ModPagespeedLogDir "/var/log/pagespeed"
ModPagespeedSslCertDirectory "/etc/ssl/certs"
ModPagespeedRewriteLevel CoreFilters
ModPagespeedEnableFilters collapse_whitespace,elide_attributes
ModPagespeedFileCacheInodeLimit        500000
ModPagespeedEnableFilters combine_css
	ModPagespeedEnableFilters rewrite_css,rewrite_javascript
	ModPagespeedEnableFilters inline_css,inline_javascript
	ModPagespeedEnableFilters rewrite_images
	ModPagespeedEnableFilters insert_img_dimensions
	ModPagespeedEnableFilters remove_comments
	ModPagespeedEnableFilters extend_cache
	ModPagespeedEnableFilters remove_quotes

        Allow from 127.0.0.1
        SetHandler pagespeed_admin
    </Location>
    <Location /pagespeed_global_admin>
        Order allow,deny
        Allow from localhost
        Allow from 127.0.0.1
        SetHandler pagespeed_global_admin
    </Location>
ModPagespeedStatisticsLogging on
 ModPagespeedMessageBufferSize 100000
</IfModule>

Here’s how I view my homepage:
Top Home 1
Top Home 2
Top Home 3

I’m waiting for your answer.
Thank you for your work.
