i deleted admin files from FTP but aslo it is blank . with vqmod , when i delete the xml file from vqmod , it was working . but for OCMOD i couldnt find the install files to delete them all . how can i fix this problem . thanks ...

Hi,
Always make a backup before any change.
You can delete an ocmod file via extension/modification.
ocmod files are stored in database. in oc_modification table. you can delete theme from there too.
You need to refresh modification after you deleted a ocmod file.

i deleted it , but it doesnt work anyway ...
do you have another suggest . website was new , only installed 2-3 module , for that reason i didint mind but , there is no error or something . a blank page , it is interesting ...

Try this:
temporary rename modification folder system\storage\modification

yes you are a genius ! it is work now , but after i changed the name to old , it doenst work again ... :/

and please can you suggest me a good module to edit modifications code . or something else ... or what can be create this problem when i want to install to my website .

i fixxed the problem i think .
after delete modification file the website works well but when refresh the Modifications from admin the store brokes again and give some errors . so ,
i delete all the modifications from Extensions>Modification ... then isntall them again ... now it works ...
