Bug since the last update (1.8)

Hi,

Since the last update (1.8) I have this error message when I try to edit a table or add a new one :

Fatal error: Uncaught Error: Call to undefined method SupsysticTables_Tables_Model_Tables::getAllTableHistory() in /homepages/43/d725327637/htdocs/wp-content/plugins/tables-generator-pro/src/SupsysticTablesPro/Tables/Module.php:177 Stack trace: #0 /homepages/43/d725327637/htdocs/wp-includes/class-wp-hook.php(286): SupsysticTablesPro_Tables_Module->onTableHistoryTabsContentData(Array) #1 /homepages/43/d725327637/htdocs/wp-includes/plugin.php(244): WP_Hook->apply_filters(Array, Array) #2 /homepages/43/d725327637/htdocs/wp-content/plugins/data-tables-generator-by-supsystic/vendor/Rsc/Dispatcher.php(89): apply_filters_ref_array('supsystic_tbl_t...', Array) #3 /homepages/43/d725327637/htdocs/wp-content/plugins/data-tables-generator-by-supsystic/src/SupsysticTables/Tables/Module.php(1062): Rsc_Dispatcher->apply('table_history_t...', Array) #4 /homepages/43/d725327637/htdocs/wp-includes/class-wp-hook.php(286): SupsysticTables_Tables_Module->afterTabsContentRendered(Object(stdClass)) #5 /homepages/43/d725327637/htdocs/wp-includes in /homepages/43/d725327637/htdocs/wp-content/plugins/tables-generator-pro/src/SupsysticTablesPro/Tables/Module.php on line 177

No changes between the two versions (OK and KO version)

Any ideas to help me ?

Ps : where can I find the older version of the plugin (1.7.xxx) ? This one worked fine.
