Ultimate Under Construction

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 94% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

   I don’t know why people are rating it low but I love this plugin, it works perfectly all the time. and the best thing is you can put any html code you want.

   This plugin will re-active itself and make your web page grey. de-activating it did not fix it. I had to de-activate and then delete the plugin entirely.

   I can type my message in the HTML box, but it was supposed to have options for making my “away” page look good. They were there on the first run, but I after the first save, they disappeared.

   It provides this nice error message too: AG Custom Admin caught a JavaScript error on this site: ___________________________________________________ ReferenceError: assignment to undeclared variable background_color source:…wp-content/plugins/ultimate-under-construction/includes/js/uuc-script.js?ver=1.1 line:10 ___________________________________________________ This error prevents AG Custom Admin plugin to work properly. To fix this, please navigate to the link above in your browser and open the source of that page (right click -> view page source) and find the line in code where it fails. In most cases this error should be fixed there. As an alternative solution, you could analyse the link above to find the plugin/theme where it was thrown. You can try to disable it or to report this error to their support. If you’re unable to fix this issue by yourself, you can also report it to AGCA support. Please select the content of the error first and press Ctrl+C(Win) or Cmd+C(Mac). Confirm this message to redirect to AGCA support page, or press Cancel to exit. Unfortunately, I’m pushed for time at the minute but I’ll probably try the plugin again at some point and give a new review.

   I installed this plugin and it broke the front page on my website, I could see my favicon and that was about it. Deactivated this plugin and it all worked again. There are no other plugins arguing with the entry point and I’m using a WooCommerce theme (Wootique).

   My site is slower when this plugin is activated and the problem comes from this page: /wp-content/plugins/ultimate-under-construction/includes/js/flipclock.min.js

   The plugin is named ‘Ulimate Under Construction page’ in the wordpress plugin list. You might want to add a t. The browser console gives several errors if you are logged in as admin, that seem to be caused by the count-down-clock code, even if you don’t have the countdown clock on. For the rest it works fine!

   Like many WP site builders, I used to use Maintenance-Mode by Michael Wöhrer for my holding/maintenance/coming soon pages. Now it’s no longer supported, I searched in vain for a similar plugin that would allow the use of a distinct, fully-coded, custom html page instead of a range of pre-designed options. THIS IS IT!! This is a super simple, really effective plugin. You can either choose a pre-coded page with fields for page background, title, message and a countdown timer, or your own html – where you can enter code for an entire html page of your own design (the plugin treats the custom html block as if it is in the root directory, so put your images there and it will work). This is great news, and fills a huge gap in the market left by the demise of Maintenance-Mode. It’s the only such plugin I have found. Many thanks indeed!
