Why is my Dropbox full?

/0 Comments/in /by

Your dropbox is full and the amount of space you are using shown in the app or web interface does not correspond to the size of the Dropbox folder on your computer. You are not using selective syncing, i.e. all folders in the Dropbox cloud should be equal to the size of the Dropbox folder on your computer.

The reason might be you are using an external USB-drive on your computer.

When external USB-drives are connected, Dropbox asks if they should be backed up. If you selected yes, the content of the USB drive is copied to Dropbox cloud and occupies your space. If this was not the intention (for example if the external drive contains a backup copy of your files in the Dropbox folder), remove the external drive from the Dropbox folder.

How to make WordPress display PHP errors

/0 Comments/in /by

Your site is down just displaying “This site is experiencing technical difficulties” and you need to investigate what is causing the error. If you turn on PHP error reporting at your hosting provider, WordPress still just displays the generic message.

Turn on PHP error reporting at your hosting provider.

Edit the wp-config.php file and comment out the line define( ‘WP_DEBUG’, false ); 

// define( 'WP_DEBUG', false );

Then add the following lines and make sure they occur before the line /* That’s all, stop editing! Happy blogging. */

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', true );
@ini_set( 'display_errors', 1 );

When you are done, remember to revert the above changes.

apt update error message “Could not execute ‘apt-key’ to verify signature”

/0 Comments/in /by

It turned out the reason for this was changed permissions on the /tmp folder (caused by restoring a folder with BackupPC to /tmp instead of it’s original location).

Solution: 

chown root:root /tmp
chmod 1777 /tmp

After this apt update worked as normal.

How to indicate where a word should wrap in HTML/CSS

/0 Comments/in /by

By using word-wrap, word-break and overflow-wrap in CSS you can control the browser’s behaviour when it comes to word wrapping. However, it is not possible to control where the word breaks. It just breaks when the word no longer fits in the container.

To indicate where a word can be broken, the soft hyphen can be used. The soft hyphen is a html code:

­

For example:

Thisisaverylongword

and we want it to break just after “very”, then we type:

Thisisavery­longword

When the container doesn’t fit the word, it will be displayed on two lines:

Thisisavery-
longword
