@dominik:
These are the relevant lines from the info.php that I saved when the problem occurred…

PHP Version 5.5.31
disable_functions shshow_source, system, shell_exec, passthru, exec, popen, proc_open, eval, symlink, link, readlink, dl, escapeshellarg, escapeshellcmd, ini_restore, apache_get_modules, get_cfg_var, ini_get_all

Now resolved for my site: My hosting company updated my PHP version to 5.6.24, and I see (via info.php) that their php.ini for this version doesn’t include any values for disable_functions.

@patrickphotosuk: We both have tickets open with Fast2Host. I’ll post an update here when I get response from them.

@james: Thanks. I’ll see what my hosting provider responds with tomorrow.

Just been Googling (to preempt possible hosting company objections to enabling the function)… Looks like it was possibly disabled due to a vulnerability in php 5.3. I’m guessing this vulnerability is now patched in current php version, but php.ini has not been updated accordingly.

A possible workaround from the coding side…

Beyond that, some great advice has already been posted here suggesting ways you might be able to fix this yourself without even bothering your hosting provider.

Please restate the ways to fix this without bothering hosting provider – I for one don’t have access to php.ini and others have written that editing wp_debug does not resolve it.

My site is hosted by https://www.fast2host.com/ (cPanel)

Same issue here. Thanks @markrh for the clue. It is indeed in the disable_functions list on my host. I’ll talk to them tomorrow.

With my limited knowledge, I think that people should not leave the info.php file present on their site for security reasons, but I may be out of date on this?

Many thanks for responding. If the title attribute is good for SEO, I’d better re-title the images rather than seek to suppress their appearance when hovering over the images. I’m still thankful for the css that Hannah supplied so that we can choose to suppress the title display in the lightbox.
Thanks again, and wishing you much joy with your newborn.

Hi Hannah, thanks for your response. Congratulations to the developer on becoming a father!

The browsers I’m using are Firefox 47.0 and Safari 9.1.2 on OSX El-Capitan. I get the same hover behaviour on both (the media title is displayed) on the wooCommerce product pages. This is on the product image and the product gallery image thumbnails.
