Apache error: .htaccess: Invalid command ‘RewriteEngine’, perhaps misspelled or defined by a module not included in the server configuration
This time a simple error and simple explanation. I installed a nice WAMP package called WampServer and I got an error on a site that worked fine on other servers. The error I found in the logs was:
.htaccess: Invalid command ‘RewriteEngine’, perhaps misspelled or defined by a module not included in the server configuration
PHP Error: unserialize() [function.unserialize]: Error at offset 118 of 512
Lately I got this error in my script while trying to decode serialized UTF-8 string:
unserialize() [function.unserialize]: Error at offset 118 of 512
Here’s a simple solution I found.
Solution to jQuery error: “this.empty is not a function”
A few days ago I was working on a quite complex editor written almost entirely in JavaScript using jQuery library. At some point I noticed a weird error in Firefox error console: “this.empty is not a function”.
The error description is quite confusing so it took a few seconds to realize what’s wrong…
jQuery error: this[0].ownerDocument is null
Recently I found a weird problem with my code. Firefox error console informed me that:
this[0].ownerDocument is null
and that this problem occurs on line 19 of the jquery.js.
PHP: How to safely include file with possible parse errors?
Recently I had written a class and it had to save bits of information somewhere. I wanted to make the script installable just by placing it on a server so I didn’t want to use any database. Instead I figured out I should save the data in a simple file. I could use serialize and file_put_contents which is very easy to write, but modifying such files manually in a text editor is a nightmare. So I decided to save the contents in a PHP file.
Unfortunately if there is an error in such file you will get parse error when including it.

PHP Error: Fatal error: Unable to read X bytes in Y.php on line 0
“Fatal error: Unable to read X bytes in Y.php on line 0″ is an error I got once after moving a site to another server. The file was encoded with Zend Optimizer so I could not check what is happening on line 0 that could make any problems.
Internal server error after placing php_value in .htaccess file?
I was recently moving a website to another server and I found out that after saving text into DB all the quotation marks were preceded by slashes.
This mean the “magic_quotes_gpc” option is enabled in the configuration file.
Here’s how to fix this behavior.
PHP Error “headers already sent”
If got an error like this one:
Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at E:\websites\index.php:3) in E:\websites\index.php on line 5
it means you tried to change headers of the file after sending the content of the file.
