If you did NOT have a backup on forehand.. you can NOT use the below part. (restore a deleted page/-s)
An export of the sql dbase is always sufficient,
( i pers. do not like software to help as it is over the top in in normal use) Always adviced before making great changes on a website (make a backup from dbase + files first) you can revert back in case it fails.. ( a dbase export takes half a minute ?) And..why not do it once a month?.... hosting does offer backups incase server issues..but that is....
Are you familair with dbases and phpadmin..? If yes.. open up the (textual backupped) database with a good editor.
Find in that listing somewhere Pages... It should be something consisting of 2 'blocks' .
The first block represents the instructions what to do if no tables exist in dbase yet (so 'build'.)
The second part (INSERT INTO) holds ALL pages (and places,links to img..etc..) in a styling that interacts (values etc..) with the databasetables...
Well anyway this part IS the content..
NOW..without adding a new tutorial (backup:keep one untouched). READ before experimenting!! You are on your own at this point....
Go to your main database server find the e107_pages table ( 2 options possible, but depends of your knowledge) you CAN DELETE (drop) this WHOLE table (opt 1) or you CAN EMPTY the tables (table content) of this PAGES TABLE..
If NO new pages were added : DELETE the whole pages table.. (keep database open and look at top for SQL (normally second tab) click on it..and STOP. (a blank field should appear)
NExt : you had opened up the sql file in an editor ? COPY the TOTAL (eg the 2 blocks) representing Pages ( so the parts starting with Create + part Insert...completly). Make sure it is complete selected.(area) No extras before OR after...
Now PASTE this in the empty field of the database window..when pasted click Start..
if you did all right.. a greenish bar should report bla blabla.. success.....anything else reporting > you miscopied, table has errors etc.. than it is somewhere wrong.. read.. it should give you errors described..)
That is all in a small package (basic).. It is how to work with/in databases and is applicable to each system is used, not related to e107 or alike..
