We have come across a problem with our site overnight where the layout of the site has changed, the store no longer works, we can no longer access our admin panel and we are receiving the following error message at the bottom of the screen.
Fatal error: spl_autoload() [<a href='function.spl-autoload'>function.spl-autoload</a>]: Class Zend_Log_Exception could not be loaded in /homepages/34/d502468010/htdocs/lib/Zend/Log/Writer/Stream.php on line 135
We have contacted our hosts and they said it would be down to a lack of storage on the database so we have cleared space and nothing has changed. We have also completed back-ups but we have not had any success.
If anyone could assist that would be great.
1. Check space on drive/partition you're using for var/ directory storage
2. Try to clear the cache by deleting var/cache directory (and var/full_page_cache for Magento Enterprise).
3. The last resort would be clearing var/session directory content, although it's not the best practice since your customer will lose cart details (if they are logged in).
