Magento – Magento 1.7. error after attempting restore to backup

magento-1.7

A frustrating mishap.
Did a backup in anticipation of testing a module install. Didn't like the module install so restored to backup.

After restore cannot login to admin. Front and back both have error as follows below. Reviewed the files by FTP. No Lib folder, no JS folder, no Media folder. Other folders are there and the contents appear to be there, but since there are hundreds of files, I've no way to know. Can I just re-install the missing folders?

Thanks to all in advance,

The file Varien/Autoload.php is located in the lib directory, so if you say you don't have it the site can't load. I would indeed copy the missing files from the installation file and see if the site will work again. You should also check your installed extensions to see if they placed something in the missing directories.

Magento – Magento 1.7 error invalid block type

If you take a look at your error call stack

#0 /home/public_html/domain.nl/includes/src/__default.php(27333):     Mage::throwException('Ongeldig blokty...')
#1 /home/public_html/domain.nl/includes/src/__default.php(27275):      Mage_Core_Model_Layout->_getBlockInstance('relatedslider/p...', Array)
#2 /home/public_html/domain.nl/includes/src/__default.php(27310):      Mage_Core_Model_Layout->createBlock('relatedslider/p...', 'magentothem_rel...')
#3 /home/public_html/domain.nl/includes/src/__default.php(27077):

most of the files involved come from the includes/src/__default.php file. Magento only uses this file when it's running in "compiler" mode. Compiler mode is when Magento looks at all the module class files in app/code/*/*, and then makes a copy of those files in includes/src — it also combines many base classes in a single file, __default.php. This is done to increase performance in production systems.

So, step one would be to disable compiler mode, see if the error has gone away, and then re-compile your classes to catch whatever class was missed in the initial compilation. You can do this at

System -> Tools -> Compilation

Or via the shell script

$ php shell/compiler.php

If the problem does not go away when compilation mode is disabled, it looks like Magento is trying to instante a block (perhaps embedded in a CMS page) that doesn't exist.

Mage_Core_Model_Layout->createBlock('relatedslider/p...', 'magentothem_rel...')

Unfortunately, this block's full class alias (relatedslider/p...) is omitted. Figuring out the full block alias, and why Magento can't instantiate it (missing class, mistyped alias, etc.) will lead you to a solution for your problem.

Magento – getting Error in magento

Check for anything in all files, before the starting <?php and if the file ends with an ?>. Remove the trailing ?>. No one needs this.

This error is often raised, because you added a space before the stating <?php

And I think in later PHP versions, they improved the error by adding the information where the output started. Think about updating php to know this.
