Warning: fopen() [function.fopen]: Unable to access /data/s/o/solvent.sk/sub/velkoobchod/system/cache/cache.product.bestseller.2.0.10.1305471803 in /data/s/o/solvent.sk/sub/velkoobchod/system/library/cache.php on line 41Warning: fopen(/data/s/o/solvent.sk/sub/velkoobchod/system/cache/cache.product.bestseller.2.0.10.1305471803) [function.fopen]: failed to open stream: No such file or directory in /data/s/o/solvent.sk/sub/velkoobchod/system/library/cache.php on line 41Warning: fwrite(): supplied argument is not a valid stream resource in /data/s/o/solvent.sk/sub/velkoobchod/system/library/cache.php on line 43Warning: fclose(): supplied argument is not a valid stream resource in /data/s/o/solvent.sk/sub/velkoobchod/system/library/cache.php on line 45Warning: fopen() [function.fopen]:

Check you CHMOD settings on that folder/file.

It needs to be writable.

chmod is 777 .. it always show error warnings .. a lot of error warnings .. you can see it on: http://velkoobchod.solvent.sk

who is your host?

can you access files via FTP?

Can you delete/edit files via FTP?

reason i ask is that error can occour when your host has disabled write permissions due to maintinance work on their servers.

my website same problem ,http://www.sathd.co.uk how can i do
thanks
