Today I updated the version of PHP I use in my development environment, from PHP 7.0.7 to PHP 7.1.1. [Read more…]
If you’re developing a Genesis child theme and making quite a few changes to your
style.css file you may want a quick and easy method of ensuring the style file is reloaded every time it gets changed.
One way is to ensure that the
ver parameter on the stylesheet definition changes each time you update the file. [Read more…]

This is a work in progress post, cloned rather prematurely from my development machine so I can refer to from my iPad when my development machine is not available. [Read more…]
For every new release of WordPress, plugin and theme developers are expected to test that their products are compatible with the new version, and to update their “Compatible up to” status. But if you have lots and lots of plugins, how do you test them all? WordPress uses a tool called PHPUnit. Plugins and themes can do the same. This post discusses the solution that I’ve been developing to PHPUnit test my WordPress plugins in situ. [Read more…]
Sometime on the 12th my site started to produce a series of PHP Fatal errors saying “Allowed memory size of 41943040 bytes exhausted.”. This was a bit of a surprise. It means that my memory limit was 40M, a lot lower than the expected value of 256M.
Other times the response was
[13-Jul-2016 02:54:59 UTC] PHP Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0
To recover from this problem I used ftp to rename Jetpack to Jetpack-f. I was then able to access the site.
- The site was migrated from one host to another.
- The PHP version on the new host was 5.4.45.
- The memory_limit was set to
- For PHP 5.3, 5.5 and 5.6 the memory_limit would have been
256M; a much nicer number.
- By the time WordPress started up the memory limit became
- It’s WordPress that sets this limit, depending on the site. For WPMS it’s
64M. See wp_initial_constants().
I’ve yet to track down the specific plugin/module combination that causes WP to exceed the 4OM limit.
- My oik-bwtrace plugin reports the memory limit on its admin page.
- This is 256M, since WordPress sets it higher in admin pages. Using admin_memory_limit in wp-admin/admin.php.
- I’ve changed my [wp] shortcode to display the memory limit on the front-end.
- For this site the memory_limit has already been set by the hosting company to a high value.
WordPress 4.7.3. PHP: 7.0.16. Memory limit: 128M
- I’m also experimenting with code that displays the current memory_limit in trace records produced by oik-bwtrace. They already optionally display current and peak memory usage, so adding the current memory limit is no big deal.
I’ve been porting a site from Drupal to WordPress recently but it wasn’t until I loaded it onto hosting with 1&1 that I noticed some problems with my [bw_show_googlemap] shortcode. I’ve fixed the problem in oik v3.0.2. The new solution requires you to obtain a Google Maps API key, and enter it in oik options. [Read more…]
In 2015 I wrote a bucket list of things to achieve before leaving WordCamp London; bucket list – post WordCamp London 2015. After the event it was much longer; bucket list – WordCamp London: 20-22 March 2015 (#wcldn). This year I’ve volunteered my services to help with the running of the event. Will I have more or less opportunity to work on my bucket list? It’s a bigger list than ever.
If you happen to know an answer, just come to find me, let me know, and then after a few more questions you can go on your way.
I’ll be wearing a blue “localhost” T-shirt, just like the other volunteers. If you can’t find me just tell another volunteer and they can either pass it on through Group Me, or look utterly bemused.
Here’s my list, in no particular order. [Read more…]

I’ve had this problem for a while now. I’m happily working away on my Windows PC, editing posts, changing code and testing and then out of the blue comes a
Fatal error: Cannot redeclare message.
But when I press Enter or refresh it goes away.
