There are 9 categories. * Strange thing is that I don’t find error from all pages. I got error from where I put following code. [wp_rss_multi_importer category=”1,2,3,4,5,6″] [wp_rss_multi_importer] * But I don’t get error from [wp_rss_multi_importer category=”1″] [wp_rss_multi_importer category=”2″] [wp_rss_multi_importer category=”3″]… * This means that I get error when I try to display multiple categories? * [http://wordpress.org/plugins/wp-rss-multi-importer/](http://wordpress.org/plugins/wp-rss-multi-importer/) Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Author [Allen](https://wordpress.org/support/users/amweiss98/) * (@amweiss98) * [12 years, 10 months ago](https://wordpress.org/support/topic/weird-error-array_merge-functionarray-merge-argument-1-is-not-an-array-i/#post-4007158) * thanks…I’ll need to look into this and see what’s going on with the beta version.

Shortcode Setting > What Shows – EXCERPTS“ Let your readers determine if they want to see the excerpt with a show-hide option.” After I replaced the file, nothing be displayed by clicking show-hide button. * Plugin Author [Allen](https://wordpress.org/support/users/amweiss98/) * (@amweiss98) * [12 years, 10 months ago](https://wordpress.org/support/topic/weird-error-array_merge-functionarray-merge-argument-1-is-not-an-array-i/#post-4007168) * you’ll need to make sure nothing is in cache…I just tried the pagination (after flushing my browser’s cache) and pagination is working fine as is the show-hide option. Nothing in the file I gave you changed either of these functions. * Thread Starter [noppresed](https://wordpress.org/support/users/noppresed/) * (@noppresed) * [12 years, 10 months ago](https://wordpress.org/support/topic/weird-error-array_merge-functionarray-merge-argument-1-is-not-an-array-i/#post-4007169) * really…yeah, I flushed cache and I used Internet Explorer that I rarely use to make it sure. But something is wrong with pagination and show-hide option. It works well after I placed back the old file. Same situation after changing theme and template. * Plugin Author [Allen](https://wordpress.org/support/users/amweiss98/) * (@amweiss98) * [12 years, 10 months ago](https://wordpress.org/support/topic/weird-error-array_merge-functionarray-merge-argument-1-is-not-an-array-i/#post-4007178) * are you using the default template theme for the shortcode – if not, that is the only template theme that supports show-hide? * Plugin Author [Allen](https://wordpress.org/support/users/amweiss98/) * (@amweiss98) * [12 years, 10 months ago](https://wordpress.org/support/topic/weird-error-array_merge-functionarray-merge-argument-1-is-not-an-array-i/#post-4007180) * also, here is a movie of what I see using 2.68, the same main file as you just downloaded, set for pagination and show-hide * [http://www.screencast.com/t/wJCkBtMH](http://www.screencast.com/t/wJCkBtMH) * It may be that you are using an older version of the beta, so if you want the newest version you can download it here * [https://dl.dropboxusercontent.com/u/3132388/beta/wp-rss-multi-importer.zip](https://dl.dropboxusercontent.com/u/3132388/beta/wp-rss-multi-importer.zip) * Thread Starter [noppresed](https://wordpress.org/support/users/noppresed/) * (@noppresed) * [12 years, 10 months ago](https://wordpress.org/support/topic/weird-error-array_merge-functionarray-merge-argument-1-is-not-an-array-i/#post-4007187) * Newest version solved the error!
