The grid I see does not match to what I built!

If you have any of the caching plugins – it is a result of caching most probably. It is best to disable caching while you are building a grid, or set something like “disable caching for logged in users” in caching plugin setup.

Why does this plugin use timthumb?

Even though using timthumb is not considered a good practice nowadays, it’s a “necessary evil” to implement some of UberGrid’s key features. Other ways known (like pre-building resized thumbnails) would have an unacceptable response time, especially in typical shared hosting environments having very limited processor resources. The only viable alternative is JetPack photon, but it has its own shortcomings like the need to install a pretty heavy JetPack plugin, and slightly blurry resulting images.

It’s recommended, though, to install JetPack, enable its Photon module and switch UberGrid to use it at UberGrid global settings.

To block timthumb after switching to Photon, you can use the process described in this article: http://www.warrenchandler.com/2013/04/01/how-to-stop-timthumb-hacks-using-htaccess/

The grid I built does not look right – there are gaps, text overlapping, etc.

Most probably that is because some of the themes process shortcode output and add there “p” tags thus breaking UberGrid layout. Try to go to Settings -> UberGrid at the admin area, and enable “Use Shortcode hack” option, it should help.

I upgraded UberGrid and see serious issues now.

This kind of problems is usually caused by caching and Javascript minifier plugins. Please do the next: 1. If your site is on WPEngine server – please make sure to clear all WPEngine caches. 2. If you’re using one of W3 Total Cache, WP Super cache or BWP Minify plugins – please disable them for a moment, make sure all works OK, and flush all caches (including BWP Minify minified file cache).

Image thumbnails look blurry

It’s a common problem happening on any resizing, if no post-resizing sharpening was applied. Even professional design software is subject for this problem. In UberGrid, you can partially resolve the problem by creating wp-content/uber-grid-timthumb-config.php file with the next contents: <?php define(DEFAULT_S, 1); Please be very careful with spelling, and note that closing PHP tag is omitted intentionally. After creating this file, you need to wait for 24 hours to make sure thumbnail cache is rebuilt, or manually clear wp-content/uber-grid-timthumb-cache or wp-content/uploads/uber-grid-timthumb-cache directory.

How do I copy UberGrids from dev site to production?

  1. Make sure all your data is backed up
  2. Open Tools -> Export at the admin area.
  3. Choose “All content” radio button.
  4. Export.
  5. Copy all the wp-content/uploads content to the production site manually.
  6. Install WordPress Importer plugin
  7. Import the file you previously exported

Black & white effect does not work

Internet Explorer versions 9, 10, and 11 do not have a support for grayscale effect, because Microsoft removed their non-standard DirectX-based filters, but did not add CSS3-compatible grayscale implementation.
