Got it. Thx! ??

Hey Benjamin. Can I come back on this issue?
The problem is still unresolved.

I cannot change themes.

Funny thing: Backend shows the theme “plana” as activated, yet the full error message relates to the “vortex”-directory:
“variable @calendarTitle is undefined in file /var/www/virtual/gruenehh/html/wordpress/wp-content/plugins/all-in-one-event-calendar/public/themes-ai1ec/vortex/less/user-variable-map.less in user-variable-map.less on line 31, column 33 29| @dropdown-link-hover-bg: @dropdownLinkBackgroundHover; 30| @input-color-placeholder: @placeholderText; 31| @calendar-title-color: @calendarTitle; 32| @today-color: @todaycolor; 33| @allday-badge-color: @alldayBadgeGradientMiddle; 34| @event-image-shadow: @eventImageShadow;”

Foxplex, thanks a lot for the get_short_date tweak! Works smoothly.

I have one more question: The time still says “pm” and “am” as in English time format, but the connector betweet date an time is “um” as in German language.
I looked for “um” and (independently) for “pm” in both the /calendar and /event folder – without succes.

Can you tell me which part to tweak to get “Uhr” instead of “pm”/”am”?

Got it myself: you have to change the blog_single-loop.php file, which is located at .../themes/stockholm/templates/blog

In the .php file, you’ll find the lines

if ( has_post_thumbnail() ) { ?>
   <div class="post_image">
   <?php the_post_thumbnail('blog_image_in_grid'); ?>
   </div>

Add the following under this:

<p align="right" class="caption" style="font-size:small"><i class="fa fa-picture-o"></i>
 <?php
 echo get_post(get_post_thumbnail_id())->post_excerpt;
 ?>
 </p>

The essential part is the <php> code. The rest changes the font, the alignment and inserts a nice font-awesome-icon.

Yep, when I hit “save changes”.

My current problem (after solving the other one)kinda fits this thread:

I cannot customize any colors (independant of the chosen theme).
The error message was lamenting about the variable @calendarTitle in the user-variable-map.less file. So I put the whole line //@calendar-title-color: @calendarTitle; in comments.

Then, the really strange error message is: variable @grayDark is undefined in file anonymous-file-2451.less in anonymous-file-2451.less

Any ideas how to handle this? :-/
[note: no cache plugin, not resolvable by flip flopping themes]

Apparition of the plugin is fixed after upgrading the plugin from 2.5.6 to 2.5.8. Thanks for that!

Same problem for me: Link

• No cache plugin
• not resolvable by flip-flopping themes
• or saving the theme settings.

When hitting “save”, an error message reads:

variable @calendarTitle is undefined in file /var/www/virtual/gruenehh/html/wordpress/wp-content/plugins/all-in-one-event-calendar/public/themes-ai1ec/vortex/less/user-variable-map.less in user-variable-map.less on line 31, column 33 29| @dropdown-link-hover-bg: @dropdownLinkBackgroundHover; 30| @input-color-placeholder: @placeholderText; 31| @calendar-title-color: @calendarTitle; 32| @today-color: @todaycolor; 33| @allday-badge-color: @alldayBadgeGradientMiddle; 34| @event-image-shadow: @eventImageShadow;

I have another project running WP 4.5.3 and the plugin version 2.5.2 – and it all works out fine.

I’ll appreciaty your advice.
