Sidebar: slideshow_layerslider.php on line 121

Hello!

On my sidebar right under a simple text widget containing the text “Day X of 45″ I get an error message in debug mode:

Undefined index: index in /home/www/doc/24619/lukyly.com/www/wp-content/themes/enfold/config-templatebuilder/avia-shortcodes/slideshow_layerslider.php on line 118 Notice: Undefined index: index in /home/www/doc/24619/lukyly.com/www/wp-content/themes/enfold/config-templatebuilder/avia-shortcodes/slideshow_layerslider.php on line 121

I think I´ve done all tips I found for resolving this error:
– set memory_limit to 128 MB
– checked file/folder rights (755)
– removed layer sider, saved and added it again (on first save everything was fine, but after adding layer slider the error came back)

HTML from firebug:
<div class=”inner_sidebar extralight-border”>
<div id=”text-8″ class=”widget clearfix widget_text”>
Notice: Undefined index: index in /home/www/doc/24619/lukyly.com/www/wp-content/themes/enfold/config-templatebuilder/avia-shortcodes/slideshow_layerslider.php on line 118 Notice: Undefined index: index in /home/www/doc/24619/lukyly.com/www/wp-content/themes/enfold/config-templatebuilder/avia-shortcodes/slideshow_layerslider.php on line 121
<div id=”text-9″ class=”widget clearfix widget_text”>
</div>

Any ideas how to solve this?
